  Bezier function generator

  This has been modified from Gaëtan Renaudeau's BezierEasing
  https://github.com/gre/bezier-easing/blob/master/src/index.js
  https://github.com/gre/bezier-easing/blob/master/LICENSE
  
  I've removed the newtonRaphsonIterate algo because in benchmarking it
  wasn't noticiably faster than binarySubdivision, indeed removing it
  usually improved times, depending on the curve.

  I also removed the lookup table, as for the added bundle size and loop we're
  only cutting ~4 or so subdivision iterations. I bumped the max iterations up
  to 12 to compensate and this still tended to be faster for no perceivable
  loss in accuracy.

  Usage
    const easeOut = cubicBezier(.17,.67,.83,.67);
    const x = easeOut(0.5); // returns 0.627...
*/
// Returns x(t) given t, x1, and x2, or y(t) given t, y1, and y2.
const calcBezier = (t, a1, a2) => (((1.0 - 3.0 * a2 + 3.0 * a1) * t + (3.0 * a2 - 6.0 * a1)) * t + 3.0 * a1) * t;
const subdivisionPrecision = 0.0000001;
const subdivisionMaxIterations = 12;
function binarySubdivide(x, lowerBound, upperBound, mX1, mX2) {
  let currentX;
  let currentT;
  let i = 0;
  do {
    currentT = lowerBound + (upperBound - lowerBound) / 2.0;
    currentX = calcBezier(currentT, mX1, mX2) - x;
    if (currentX > 0.0) {
      upperBound = currentT;
    } else {
      lowerBound = currentT;
    }
  } while (Math.abs(currentX) > subdivisionPrecision && ++i < subdivisionMaxIterations);
  return currentT;
}
function cubicBezier(mX1, mY1, mX2, mY2) {
  // If this is a linear gradient, return linear easing
  if (mX1 === mY1 && mX2 === mY2) return _motionone_utils__WEBPACK_IMPORTED_MODULE_0__.noopReturn;
  const getTForX = aX => binarySubdivide(aX, 0, 1, mX1, mX2);
  // If animation is at start/end, return t without easing
  return t => t === 0 || t === 1 ? t : calcBezier(getTForX(t), mY1, mY2);

/**
 * Specifies automatic styling.
 *
 * @publicApi
 */
const AUTO_STYLE = '*';
/**
 * Creates a named animation trigger, containing a  list of [`state()`](api/animations/state)
 * and `transition()` entries to be evaluated when the expression
 * bound to the trigger changes.
 *
 * @param name An identifying string.
 * @param definitions  An animation definition object, containing an array of
 * [`state()`](api/animations/state) and `transition()` declarations.
 *
 * @return An object that encapsulates the trigger data.
 *
 * @usageNotes
 * Define an animation trigger in the `animations` section of `@Component` metadata.
 * In the template, reference the trigger by name and bind it to a trigger expression that
 * evaluates to a defined animation state, using the following format:
 *
 * `[@triggerName]="expression"`
 *
 * Animation trigger bindings convert all values to strings, and then match the
 * previous and current values against any linked transitions.
 * Booleans can be specified as `1` or `true` and `0` or `false`.
 *
 * ### Usage Example
 *
 * The following example creates an animation trigger reference based on the provided
 * name value.
 * The provided animation value is expected to be an array consisting of state and
 * transition declarations.
 *
 * ```typescript
 * @Component({
 *   selector: "my-component",
 *   templateUrl: "my-component-tpl.html",
 *   animations: [
 *     trigger("myAnimationTrigger", [
 *       state(...),
 *       state(...),
 *       transition(...),
 *       transition(...)
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "something";
 * }
 * ```
 *
 * The template associated with this component makes use of the defined trigger
 * by binding to an element within its template code.
 *
 * ```html
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * ### Using an inline function
 * The `transition` animation method also supports reading an inline function which can decide
 * if its associated animation should be run.
 *
 * ```typescript
 * // this method is run each time the `myAnimationTrigger` trigger value changes.
 * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
 string]: any}): boolean {
 *   // notice that `element` and `params` are also available here
 *   return toState == 'yes-please-animate';
 * }
 *
 * @Component({
 *   selector: 'my-component',
 *   templateUrl: 'my-component-tpl.html',
 *   animations: [
 *     trigger('myAnimationTrigger', [
 *       transition(myInlineMatcherFn, [
 *         // the animation sequence code
 *       ]),
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "yes-please-animate";
 * }
 * ```
 *
 * ### Disabling Animations
 * When true, the special animation control binding `@.disabled` binding prevents
 * all animations from rendering.
 * Place the  `@.disabled` binding on an element to disable
 * animations on the element itself, as well as any inner animation triggers
 * within the element.
 *
 * The following example shows how to use this feature:
 *
 * ```typescript
 * @Component({
 *   selector: 'my-component',
 *   template: `
 *     <div [@.disabled]="isDisabled">
 *       <div [@childAnimation]="exp"></div>
 *     </div>
 *   `,
 *   animations: [
 *     trigger("childAnimation", [
 *       // ...
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   isDisabled = true;
 *   exp = '...';
 * }
 * ```
 *
 * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,
 * along with any inner animations.
 *
 * ### Disable animations application-wide
 * When an area of the template is set to have animations disabled,
 * **all** inner components have their animations disabled as well.
 * This means that you can disable all animations for an app
 * by placing a host binding set on `@.disabled` on the topmost Angular component.
 *
 * ```typescript
 * import {Component, HostBinding} from '@angular/core';
 *
 * @Component({
 *   selector: 'app-component',
 *   templateUrl: 'app.component.html',
 * })
 * class AppComponent {
 *   @HostBinding('@.disabled')
 *   public animationsDisabled = true;
 * }
 * ```
 *
 * ### Overriding disablement of inner animations
 * Despite inner animations being disabled, a parent animation can `query()`
 * for inner elements located in disabled areas of the template and still animate
 * them if needed. This is also the case for when a sub animation is
 * queried by a parent and then later animated using `animateChild()`.
 *
 * ### Detecting when an animation is disabled
 * If a region of the DOM (or the entire application) has its animations disabled, the animation
 * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides
 * an instance of an `AnimationEvent`. If animations are disabled,
 * the `.disabled` flag on the event is true.

/**
 * Defines an animation step that combines styling information with timing information.
 *
 * @param timings Sets `AnimateTimings` for the parent animation.
 * A string in the format "duration [delay] [easing]".
 *  - Duration and delay are expressed as a number and optional time unit,
 * such as "1s" or "10ms" for one second and 10 milliseconds, respectively.
 * The default unit is milliseconds.
 *  - The easing value controls how the animation accelerates and decelerates
 * during its runtime. Value is one of  `ease`, `ease-in`, `ease-out`,
 * `ease-in-out`, or a `cubic-bezier()` function call.
 * If not supplied, no easing is applied.
 *
 * For example, the string "1s 100ms ease-out" specifies a duration of
 * 1000 milliseconds, and delay of 100 ms, and the "ease-out" easing style,
 * which decelerates near the end of the duration.
 * @param styles Sets AnimationStyles for the parent animation.
 * A function call to either `style()` or `keyframes()`
 * that returns a collection of CSS style entries to be applied to the parent animation.
 * When null, uses the styles from the destination state.
 * This is useful when describing an animation step that will complete an animation;
 * see "Animating to the final state" in `transitions()`.
 * @returns An object that encapsulates the animation step.
 *
 * @usageNotes
 * Call within an animation `sequence()`, `{@link animations/group group()}`, or
 * `transition()` call to specify an animation step
 * that applies given style data to the parent animation for a given amount of time.
 *
 * ### Syntax Examples
 * **Timing examples**
 *
 * The following examples show various `timings` specifications.
 * - `animate(500)` : Duration is 500 milliseconds.
 * - `animate("1s")` : Duration is 1000 milliseconds.
 * - `animate("100ms 0.5s")` : Duration is 100 milliseconds, delay is 500 milliseconds.
 * - `animate("5s ease-in")` : Duration is 5000 milliseconds, easing in.
 * - `animate("5s 10ms cubic-bezier(.17,.67,.88,.1)")` : Duration is 5000 milliseconds, delay is 10
 * milliseconds, easing according to a bezier curve.
 *
 * **Style examples**
 *
 * The following example calls `style()` to set a single CSS style.
 * ```typescript
 * animate(500, style({ background: "red" }))
 * ```
 * The following example calls `keyframes()` to set a CSS style
 * to different values for successive keyframes.
 * ```typescript
 * animate(500, keyframes(
 *  [
 *   style({ background: "blue" }),
 *   style({ background: "red" })
 *  ])

 *
 * @usageNotes
 *
 * ### State Change Expression
 *
 * The State Change Expression instructs Angular when to run the transition's animations, it can
 *either be
 *  - a string with a specific syntax
 *  - or a function that compares the previous and current state (value of the expression bound to
 *    the element's trigger) and returns `true` if the transition should occur or `false` otherwise
 *
 * The string format can be:
 *  - `fromState => toState`, which indicates that the transition's animations should occur then the
 *    expression bound to the trigger's element goes from `fromState` to `toState`
 *
 *    _Example:_
 *      ```typescript
 *        transition('open => closed', animate('.5s ease-out', style({ height: 0 }) ))
 *      ```
 *
 *  - `fromState <=> toState`, which indicates that the transition's animations should occur then
 *    the expression bound to the trigger's element goes from `fromState` to `toState` or vice versa
 *
 *    _Example:_
 *      ```typescript
 *        transition('enabled <=> disabled', animate('1s cubic-bezier(0.8,0.3,0,1)'))
 *      ```
 *
 *  - `:enter`/`:leave`, which indicates that the transition's animations should occur when the
 *    element enters or exists the DOM
 *
 *    _Example:_
 *      ```typescript
 *        transition(':enter', [
 *          style({ opacity: 0 }),
 *          animate('500ms', style({ opacity: 1 }))
 *        ])
 *      ```
 *
 *  - `:increment`/`:decrement`, which indicates that the transition's animations should occur when
 *    the numerical expression bound to the trigger's element has increased in value or decreased
 *
 *    _Example:_
 *      ```typescript
 *        transition(':increment', query('@counter', animateChild()))
 *      ```
 *
 *  - a sequence of any of the above divided by commas, which indicates that transition's animations
 *    should occur whenever one of the state change expressions matches
 *
 *    _Example:_
 *      ```typescript
 *        transition(':increment, * => enabled, :enter', animate('1s ease', keyframes([
 *          style({ transform: 'scale(1)', offset: 0}),
 *          style({ transform: 'scale(1.1)', offset: 0.7}),
 *          style({ transform: 'scale(1)', offset: 1})
 *        ]))),
 *      ```
 *
 * Also note that in such context:
 *  - `void` can be used to indicate the absence of the element
 *  - asterisks can be used as wildcards that match any state
 *  - (as a consequence of the above, `void => *` is equivalent to `:enter` and `* => void` is
 *    equivalent to `:leave`)
 *  - `true` and `false` also match expression values of `1` and `0` respectively (but do not match
 *    _truthy_ and _falsy_ values)
 *
 * <div class="alert is-helpful">
 *
 *  Be careful about entering end leaving elements as their transitions present a common
 *  pitfall for developers.
 *
 *  Note that when an element with a trigger enters the DOM its `:enter` transition always
 *  gets executed, but its `:leave` transition will not be executed if the element is removed
 *  alongside its parent (as it will be removed "without warning" before its transition has
 *  a chance to be executed, the only way that such transition can occur is if the element
 *  is exiting the DOM on its own).
 *
 *
 * </div>
 *
 * ### Animating to a Final State
 *
 * If the final step in a transition is a call to `animate()` that uses a timing value
 * with no `style` data, that step is automatically considered the final animation arc,
 * for the element to reach the final state, in such case Angular automatically adds or removes
 * CSS styles to ensure that the element is in the correct final state.
 *
 *
 * ### Usage Examples
 *
 *  - Transition animations applied based on
 *    the trigger's expression value
 *
 *   ```HTML
 *   <div [@myAnimationTrigger]="myStatusExp">
 *    ...
 *   </div>
 *   ```
 *
 *   ```typescript
 *   trigger("myAnimationTrigger", [
 *     ..., // states
 *     transition("on => off, open => closed", animate(500)),
 *     transition("* <=> error", query('.indicator', animateChild()))
 *   ])
 *   ```
 *
 *  - Transition animations applied based on custom logic dependent
 *    on the trigger's expression value and provided parameters
 *
 *    ```HTML
 *    <div [@myAnimationTrigger]="{
 *     value: stepName,
 *     params: { target: currentTarget }
 *    }">
 *     ...
 *    </div>
 *    ```
 *
 *    ```typescript
 *    trigger("myAnimationTrigger", [
 *      ..., // states
 *      transition(
 *        (fromState, toState, _element, params) =>
 *          ['firststep', 'laststep'].includes(fromState.toLowerCase())
 *          && toState === params?.['target'],
 *        animate('1s')
 *      )
 *    ])
 *    ```

 *  query(':self, .record:enter, .record:leave, @subTrigger', [...])
 * ```
 *
 * The `query()` function collects multiple elements and works internally by using
 * `element.querySelectorAll`. Use the `limit` field of an options object to limit
 * the total number of items to be collected. For example:
 *
 * ```js
 * query('div', [
 *   animate(...),
 *   animate(...)
 * ], { limit: 1 })
 * ```
 *
 * By default, throws an error when zero items are found. Set the
 * `optional` flag to ignore this error. For example:
 *
 * ```js
 * query('.some-element-that-may-not-be-there', [
 *   animate(...),
 *   animate(...)
 * ], { optional: true })
 * ```
 *
 * ### Entering and Leaving Elements
 *
 * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones
 * that can are those that Angular assumes can enter/leave based on their own logic
 * (if their insertion/removal is simply a consequence of that of their parent they
 * should be queried via a different token in their parent's `:enter`/`:leave` transitions).
 *
 * The only elements Angular assumes can enter/leave based on their own logic (thus the only
 * ones that can be queried via the `:enter` and `:leave` tokens) are:
 *  - Those inserted dynamically (via `ViewContainerRef`)
 *  - Those that have a structural directive (which, under the hood, are a subset of the above ones)
 *
 * <div class="alert is-helpful">
 *
 *  Note that elements will be successfully queried via `:enter`/`:leave` even if their
 *  insertion/removal is not done manually via `ViewContainerRef`or caused by their structural
 *  directive (e.g. they enter/exit alongside their parent).
 *
 * </div>
 *
 * <div class="alert is-important">
 *
 *  There is an exception to what previously mentioned, besides elements entering/leaving based on
 *  their own logic, elements with an animation trigger can always be queried via `:leave` when
 * their parent is also leaving.
 *
 * </div>
 *
 * ### Usage Example
 *
 * The following example queries for inner elements and animates them
 * individually using `animate()`.
 *
 * ```typescript
 * @Component({
 *   selector: 'inner',
 *   template: `
 *     <div [@queryAnimation]="exp">
 *       <h1>Title</h1>
 *       <div class="content">
 *         Blah blah blah
 *       </div>
 *     </div>
 *   `,
 *   animations: [
 *    trigger('queryAnimation', [
 *      transition('* => goAnimate', [
 *        // hide the inner elements
 *        query('h1', style({ opacity: 0 })),
 *        query('.content', style({ opacity: 0 })),
 *
 *        // animate the inner elements in, one by one
 *        query('h1', animate(1000, style({ opacity: 1 }))),
 *        query('.content', animate(1000, style({ opacity: 1 }))),
 *      ])
 *    ])
 *  ]
 * })
 * class Cmp {
 *   exp = '';
 *
 *   goAnimate() {
 *     this.exp = 'goAnimate';
 *   }
 * }
 * ```
 *
 * @publicApi
 */

/**
 * Use within an animation `query()` call to issue a timing gap after
 * each queried item is animated.
 *
 * @param timings A delay value.
 * @param animation One ore more animation steps.
 * @returns An object that encapsulates the stagger data.
 *
 * @usageNotes
 * In the following example, a container element wraps a list of items stamped out
 * by an `ngFor`. The container element contains an animation trigger that will later be set
 * to query for each of the inner items.
 *
 * Each time items are added, the opacity fade-in animation runs,
 * and each removed item is faded out.
 * When either of these animations occur, the stagger effect is
 * applied after each item's animation is started.
 *
 * ```html
 * <!-- list.component.html -->
 * <button (click)="toggle()">Show / Hide Items</button>
 * <hr />
 * <div [@listAnimation]="items.length">
 *   <div *ngFor="let item of items">
 *     {{ item }}
 *   </div>
 * </div>
 * ```
 *
 * Here is the component code:
 *
 * ```typescript
 * import {trigger, transition, style, animate, query, stagger} from '@angular/animations';
 * @Component({
 *   templateUrl: 'list.component.html',
 *   animations: [
 *     trigger('listAnimation', [
 *     ...
 *     ])
 *   ]
 * })
 * class ListComponent {
 *   items = [];
 *
 *   showItems() {
 *     this.items = [0,1,2,3,4];
 *   }
 *
 *   hideItems() {
 *     this.items = [];
 *   }
 *
 *   toggle() {
 *     this.items.length ? this.hideItems() : this.showItems();
 *    }
 *  }
 * ```
 *
 * Here is the animation trigger code:
 *
 * ```typescript
 * trigger('listAnimation', [
 *   transition('* => *', [ // each time the binding value changes
 *     query(':leave', [
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 0 }))
 *       ])
 *     ]),
 *     query(':enter', [
 *       style({ opacity: 0 }),
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 1 }))
 *       ])
 *     ])
 *   ])
 * ])
 * ```

/**
 * An injectable service that produces an animation sequence programmatically within an
 * Angular component or directive.
 * Provided by the `BrowserAnimationsModule` or `NoopAnimationsModule`.
 *
 * @usageNotes
 *
 * To use this service, add it to your component or directive as a dependency.
 * The service is instantiated along with your component.
 *
 * Apps do not typically need to create their own animation players, but if you
 * do need to, follow these steps:
 *
 * 1. Use the <code>[AnimationBuilder.build](api/animations/AnimationBuilder#build)()</code> method
 * to create a programmatic animation. The method returns an `AnimationFactory` instance.
 *
 * 2. Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.
 *
 * 3. Use the player object to control the animation programmatically.
 *
 * For example:
 *
 * ```ts
 * // import the service from BrowserAnimationsModule
 * import {AnimationBuilder} from '@angular/animations';
 * // require the service as a dependency
 * class MyCmp {
 *   constructor(private _builder: AnimationBuilder) {}
 *
 *   makeAnimation(element: any) {
 *     // first define a reusable animation
 *     const myAnimation = this._builder.build([
 *       style({ width: 0 }),
 *       animate(1000, style({ width: '100px' }))
 *     ]);
 *
 *     // use the returned factory object to create a player
 *     const player = myAnimation.create(element);
 *
 *     player.play();
 *   }
 * }
 * ```

/*
 * [Validation]
 * The visitor code below will traverse the animation AST generated by the animation verb functions
 * (the output is a tree of objects) and attempt to perform a series of validations on the data. The
 * following corner-cases will be validated:
 *
 * 1. Overlap of animations
 * Given that a CSS property cannot be animated in more than one place at the same time, it's
 * important that this behavior is detected and validated. The way in which this occurs is that
 * each time a style property is examined, a string-map containing the property will be updated with
 * the start and end times for when the property is used within an animation step.
 *
 * If there are two or more parallel animations that are currently running (these are invoked by the
 * group()) on the same element then the validator will throw an error. Since the start/end timing
 * values are collected for each property then if the current animation step is animating the same
 * property and its timing values fall anywhere into the window of time that the property is
 * currently being animated within then this is what causes an error.
 *
 * 2. Timing values
 * The validator will validate to see if a timing value of `duration delay easing` or
 * `durationNumber` is valid or not.
 *
 * (note that upon validation the code below will replace the timing data with an object containing
 * {duration,delay,easing}.
 *
 * 3. Offset Validation
 * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
 * Offsets within keyframes() are considered valid when:
 *
 *   - No offsets are used at all
 *   - Each style() entry contains an offset value
 *   - Each offset is between 0 and 1
 *   - Each offset is greater to or equal than the previous one
 *
 * Otherwise an error will be thrown.

/*
 * The code within this file aims to generate web-animations-compatible keyframes from Angular's
 * animation DSL code.
 *
 * The code below will be converted from:
 *
 * ```
 * sequence([
 *   style({ opacity: 0 }),
 *   animate(1000, style({ opacity: 0 }))
 * ])
 * ```
 *
 * To:
 * ```
 * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
 * duration = 1000
 * delay = 0
 * easing = ''
 * ```
 *
 * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
 * combination of AST traversal and merge-sort-like algorithms are used.
 *
 * [AST Traversal]
 * Each of the animation verbs, when executed, will return an string-map object representing what
 * type of action it is (style, animate, group, etc...) and the data associated with it. This means
 * that when functional composition mix of these functions is evaluated (like in the example above)
 * then it will end up producing a tree of objects representing the animation itself.
 *
 * When this animation object tree is processed by the visitor code below it will visit each of the
 * verb statements within the visitor. And during each visit it will build the context of the
 * animation keyframes by interacting with the `TimelineBuilder`.
 *
 * [TimelineBuilder]
 * This class is responsible for tracking the styles and building a series of keyframe objects for a
 * timeline between a start and end time. The builder starts off with an initial timeline and each
 * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a
 * `sequence()` then it will generate a sub timeline for each step as well as a new one after
 * they are complete.
 *
 * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
 * timeline was created (based on one of the cases above) then the parent timeline will attempt to
 * merge the styles used within the sub timelines into itself (only with group() this will happen).
 * This happens with a merge operation (much like how the merge works in mergeSort) and it will only
 * copy the most recently used styles from the sub timelines into the parent timeline. This ensures
 * that if the styles are used later on in another phase of the animation then they will be the most
 * up-to-date values.
 *
 * [How Missing Styles Are Updated]
 * Each timeline has a `backFill` property which is responsible for filling in new styles into
 * already processed keyframes if a new style shows up later within the animation sequence.
 *
 * ```
 * sequence([
 *   style({ width: 0 }),
 *   animate(1000, style({ width: 100 })),
 *   animate(1000, style({ width: 200 })),
 *   animate(1000, style({ width: 300 }))
 *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
 * else
 * ])
 * ```
 *
 * What is happening here is that the `height` value is added later in the sequence, but is missing
 * from all previous animation steps. Therefore when a keyframe is created it would also be missing
 * from all previous keyframes up until where it is first used. For the timeline keyframe generation
 * to properly fill in the style it will place the previous value (the value from the parent
 * timeline) or a default value of `*` into the backFill map. The `copyStyles` method in util.ts
 * handles propagating that backfill map to the styles object.
 *
 * When a sub-timeline is created it will have its own backFill property. This is done so that
 * styles present within the sub-timeline do not accidentally seep into the previous/future timeline
 * keyframes
 *
 * [Validation]
 * The code in this file is not responsible for validation. That functionality happens with within
 * the `AnimationValidatorVisitor` code.

  The NgClass directive uses the custom change detection algorithm for its inputs. The custom
  algorithm is necessary since inputs are represented as complex object or arrays that need to be
  deeply-compared.
     This algorithm is perf-sensitive since NgClass is used very frequently and its poor performance
  might negatively impact runtime performance of the entire change detection cycle. The design of
  this algorithm is making sure that:
  - there is no unnecessary DOM manipulation (CSS classes are added / removed from the DOM only when
  needed), even if references to bound objects change;
  - there is no memory allocation if nothing changes (even relatively modest memory allocation
  during the change detection cycle can result in GC pauses for some of the CD cycles).
     The algorithm works by iterating over the set of bound classes, staring with [class] binding and
  then going over [ngClass] binding. For each CSS class name:
  - check if it was seen before (this information is tracked in the state map) and if its value
  changed;
  - mark it as "touched" - names that are not marked are not present in the latest set of binding
  and we can remove such class name from the internal data structures;
     After iteration over all the CSS class names we've got data structure with all the information
  necessary to synchronize changes to the DOM - it is enough to iterate over the state map, flush
  changes to the DOM and reset internal data structures so those are ready for the next change
  detection cycle.

/**
 * Instantiates a {@link Component} type and inserts its Host View into the current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will be destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInputs`: Optional component inputs object, which will be bind to the
 * component.
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if it exists.
 *
 * * `ngComponentOutletNgModule`: Optional NgModule class reference to allow loading another
 * module dynamically, then loading a component from that module.
 *
 * * `ngComponentOutletNgModuleFactory`: Deprecated config option that allows providing optional
 * NgModule factory to allow loading another module dynamically, then loading a component from that
 * module. Use `ngComponentOutletNgModule` instead.
 *
 * ### Syntax
 *
 * Simple
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * With inputs
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   inputs: inputsExpression;">
 * </ng-container>
 * ```
 *
 * Customized injector/content
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized NgModule reference
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModule: ngModuleClass;">
 * </ng-container>
 * ```
 *
 * ### A simple example

/**
 * A [structural directive](guide/structural-directives) that renders
 * a template for each item in a collection.
 * The directive is placed on an element, which becomes the parent
 * of the cloned templates.
 *
 * The `ngForOf` directive is generally used in the
 * [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
 * In this form, the template to be rendered for each iteration is the content
 * of an anchor element containing the directive.
 *
 * The following example shows the shorthand syntax with some options,
 * contained in an `<li>` element.
 *
 * ```
 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
 * ```
 *
 * The shorthand form expands into a long form that uses the `ngForOf` selector
 * on an `<ng-template>` element.
 * The content of the `<ng-template>` element is the `<li>` element that held the
 * short-form directive.
 *
 * Here is the expanded version of the short-form example.
 *
 * ```
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * Angular automatically expands the shorthand syntax as it compiles the template.
 * The context for each embedded view is logically merged to the current component
 * context according to its lexical position.
 *
 * When using the shorthand syntax, Angular allows only [one structural directive
 * on an element](guide/structural-directives#one-per-element).
 * If you want to iterate conditionally, for example,
 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
 * For further discussion, see
 * [Structural Directives](guide/structural-directives#one-per-element).
 *
 * @usageNotes
 *
 * ### Local variables
 *
 * `NgForOf` provides exported values that can be aliased to local variables.
 * For example:
 *
 *  ```
 * <li *ngFor="let user of users; index as i; first as isFirst">
 *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
 * </li>
 * ```
 *
 * The following exported values can be aliased to local variables:
 *
 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
 * more complex then a property access, for example when using the async pipe (`userStreams |
 * async`).
 * - `index: number`: The index of the current item in the iterable.
 * - `count: number`: The length of the iterable.
 * - `first: boolean`: True when the item is the first item in the iterable.
 * - `last: boolean`: True when the item is the last item in the iterable.
 * - `even: boolean`: True when the item has an even index in the iterable.
 * - `odd: boolean`: True when the item has an odd index in the iterable.
 *
 * ### Change propagation
 *
 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
 * those changes in the DOM. This has important implications for animations and any stateful
 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
 *
 * The identities of elements in the iterator can change while the data does not.
 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted).
 *
 * To avoid this expensive operation, you can customize the default tracking algorithm.
 * by supplying the `trackBy` option to `NgForOf`.
 * `trackBy` takes a function that has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.
 *

 * @ngModule CommonModule

 * A structural directive that conditionally includes a template based on the value of

 * When the expression evaluates to true, Angular renders the template
 * provided in a `then` clause, and when  false or null,

 * template for the `else` clause is blank.
 *
 * A [shorthand form](guide/structural-directives#asterisk) of the directive,
 * `*ngIf="condition"`, is generally used, provided
 * as an attribute of the anchor element for the inserted template.
 * Angular expands this into a more explicit version, in which the anchor element
 * is contained in an `<ng-template>` element.
 *
 * Simple form with shorthand syntax:
 *
 * ```
 * <div *ngIf="condition">Content to render when condition is true.</div>
 * ```
 *
 * Simple form with expanded syntax:
 *
 * ```
 * <ng-template [ngIf]="condition"><div>Content to render when condition is

 * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Form with storing the value locally:
 *
 * ```
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
 * ```
 *
 * @usageNotes
 *
 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
 * as seen in the following  example.
 * The default `else` template is blank.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * To display a template when `expression` evaluates to false, use an `else` template
 * binding as shown in the following example.
 * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
 * The template can be defined anywhere in the component view, but is typically placed right after
 * `ngIf` for readability.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
 *
 * ### Using an external `then` template
 *
 * In the previous example, the then-clause template is specified inline, as the content of the
 * tag that contains the `ngIf` directive. You can also specify a template that is defined
 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
 * change which template to use at runtime, as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing a conditional result in a variable
 *
 * You might want to show a set of properties from the same object. If you are waiting
 * for asynchronous data, the object can be undefined.
 * In this case, you can use `ngIf` and store the result of the condition in a local
 * variable as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * This code uses only one `AsyncPipe`, so only one subscription is created.
 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
 * You can then bind the local `user` repeatedly.
 *
 * The conditional displays the data only if `userStream` returns a value,
 * so you don't need to use the
 * safe-navigation-operator (`?.`)
 * to guard against null values when accessing properties.
 * You can display an alternative template while waiting for the data.
 *
 * ### Shorthand syntax
 *
 * The shorthand syntax `*ngIf` expands into two separate template specifications
 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
 * that is meant to show a loading page while waiting for data to be loaded.
 *
 * ```
 * <div class="hero-list" *ngIf="heroes else loading">
 *  ...
 * </div>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * You can see that the "else" clause references the `<ng-template>`
 * with the `#loading` label, and the template for the "then" clause
 * is provided as the content of the anchor element.
 *
 * However, when Angular expands the shorthand syntax, it creates
 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
 * The anchor element containing the template for the "then" clause becomes
 * the content of this unlabeled `<ng-template>` tag.
 *
 * ```
 * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
 *  <div class="hero-list">
 *   ...
 *  </div>
 * </ng-template>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * The presence of the implicit template object has implications for the nesting of
 * structural directives. For more on this subject, see
 * [Structural Directives](guide/structural-directives#one-per-element).

 * @description
 * The `[ngSwitch]` directive on a container specifies an expression to match against.
 * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
 * - Every view that matches is rendered.
 * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
 * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
 * or `ngSwitchDefault` directive are preserved at the location.
 *
 * @usageNotes
 * Define a container element for the directive, and specify the switch expression
 * to match against as an attribute:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 * ```
 *
 * Within the container, `*ngSwitchCase` statements specify the match expressions
 * as attributes. Include `*ngSwitchDefault` as the final case.
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
 * ...
 *    <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * ### Usage Examples
 *
 * The following example shows how to use more than one case to display the same view:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *   <!-- the same view can be shown in more than one case -->
 *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>

/**
 * @ngModule CommonModule
 * @description
 *
 * Unwraps a value from an asynchronous primitive.
 *
 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
 * potential memory leaks. When the reference of the expression changes, the `async` pipe
 * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
 *
 * @usageNotes
 *
 * ### Examples
 *
 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
 * promise.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
 *
 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
 * to the view. The Observable continuously updates the view with the current time.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

/**
 * @ngModule CommonModule
 * @description
 *
 * Formats a date value according to locale rules.
 *
 * `DatePipe` is executed only when it detects a pure change to the input value.
 * A pure change is either a change to a primitive input value
 * (such as `String`, `Number`, `Boolean`, or `Symbol`),
 * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
 *
 * Note that mutating a `Date` object does not cause the pipe to be rendered again.
 * To ensure that the pipe is executed, you must create a new `Date` object.
 *
 * Only the `en-US` locale data comes with Angular. To localize dates
 * in another language, you must import the corresponding locale data.
 * See the [I18n guide](guide/i18n-common-format-data-locale) for more information.
 *
 * The time zone of the formatted value can be specified either by passing it in as the second
 * parameter of the pipe, or by setting the default through the `DATE_PIPE_DEFAULT_OPTIONS`
 * injection token. The value that is passed in as the second parameter takes precedence over
 * the one defined using the injection token.
 *
 * @see {@link formatDate}
 *
 *
 * @usageNotes
 *
 * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
 * reformat the date on every change-detection cycle, treat the date as an immutable object
 * and change the reference when the pipe needs to run again.
 *
 * ### Pre-defined format options

 * ### Format examples
 *
 * These examples transform a date into various formats,
 * assuming that `dateObj` is a JavaScript `Date` object for
 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
 * given in the local time for the `en-US` locale.
 *
 * ```
 * {{ dateObj | date }}               // output is 'Jun 15, 2015'
 * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
 * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
 * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
 * {{ dateObj | date:"MMM dd, yyyy 'at' hh:mm a" }}  // output is 'Jun 15, 2015 at 09:43 PM'
 * ```
 *
 * ### Usage example
 *
 * The following component uses a date pipe to display the current date in different formats.
 *
 * ```
 * @Component({
 *  selector: 'date-pipe',
 *  template: `<div>
 *    <p>Today is {{today | date}}</p>
 *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
 *    <p>The time is {{today | date:'h:mm a z'}}</p>
 *  </div>`
 * })
 * // Get the current date and time as a date-time value.
 * export class DatePipeComponent {
 *   today: number = Date.now();
 * }
 * ```

   * such as `USD` for the US dollar and `EUR` for the euro. The default currency code can be
   * configured using the `DEFAULT_CURRENCY_CODE` injection token.
   * @param display The format for the currency indicator. One of the following:
   *   - `code`: Show the code (such as `USD`).
   *   - `symbol`(default): Show the symbol (such as `$`).
   *   - `symbol-narrow`: Use the narrow symbol for locales that have two symbols for their
   * currency.
   * For example, the Canadian dollar CAD has the symbol `CA$` and the symbol-narrow `$`. If the
   * locale has no narrow symbol, uses the standard symbol for the locale.
   *   - String: Use the given string value instead of a code or a symbol.
   * For example, an empty string will suppress the currency & symbol.
   *   - Boolean (marked deprecated in v5): `true` for symbol and false for `code`.
   *
   * @param digitsInfo Decimal representation options, specified by a string
   * in the following format:<br>
   * <code>{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}</code>.
   *   - `minIntegerDigits`: The minimum number of integer digits before the decimal point.
   * Default is `1`.
   *   - `minFractionDigits`: The minimum number of digits after the decimal point.
   * Default is `2`.
   *   - `maxFractionDigits`: The maximum number of digits after the decimal point.
   * Default is `2`.
   * If not provided, the number will be formatted with the proper amount of digits,
   * depending on what the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) specifies.
   * For example, the Canadian dollar has 2 digits, whereas the Chilean peso has none.
   * @param locale A locale code for the locale format rules to use.
   * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
   * See [Setting your app locale](guide/i18n-common-locale-id).

/**
 * Directive that improves image loading performance by enforcing best practices.
 *
 * `NgOptimizedImage` ensures that the loading of the Largest Contentful Paint (LCP) image is
 * prioritized by:
 * - Automatically setting the `fetchpriority` attribute on the `<img>` tag
 * - Lazy loading non-priority images by default
 * - Automatically generating a preconnect link tag in the document head
 *
 * In addition, the directive:
 * - Generates appropriate asset URLs if a corresponding `ImageLoader` function is provided
 * - Automatically generates a srcset
 * - Requires that `width` and `height` are set
 * - Warns if `width` or `height` have been set incorrectly
 * - Warns if the image will be visually distorted when rendered
 *
 * @usageNotes
 * The `NgOptimizedImage` directive is marked as [standalone](guide/standalone-components) and can
 * be imported directly.
 *
 * Follow the steps below to enable and use the directive:
 * 1. Import it into the necessary NgModule or a standalone Component.
 * 2. Optionally provide an `ImageLoader` if you use an image hosting service.
 * 3. Update the necessary `<img>` tags in templates and replace `src` attributes with `ngSrc`.
 * Using a `ngSrc` allows the directive to control when the `src` gets set, which triggers an image
 * download.
 *
 * Step 1: import the `NgOptimizedImage` directive.
 *
 * ```typescript
 * import { NgOptimizedImage } from '@angular/common';
 *
 * // Include it into the necessary NgModule
 * @NgModule({
 *   imports: [NgOptimizedImage],
 * })
 * class AppModule {}
 *
 * // ... or a standalone Component
 * @Component({
 *   standalone: true
 *   imports: [NgOptimizedImage],
 * })
 * class MyStandaloneComponent {}
 * ```
 *
 * Step 2: configure a loader.
 *
 * To use the **default loader**: no additional code changes are necessary. The URL returned by the
 * generic loader will always match the value of "src". In other words, this loader applies no
 * transformations to the resource URL and the value of the `ngSrc` attribute will be used as is.
 *
 * To use an existing loader for a **third-party image service**: add the provider factory for your
 * chosen service to the `providers` array. In the example below, the Imgix loader is used:
 *
 * ```typescript
 * import {provideImgixLoader} from '@angular/common';
 *
 * // Call the function and add the result to the `providers` array:
 * providers: [
 *   provideImgixLoader("https://my.base.url/"),
 * ],
 * ```
 *
 * The `NgOptimizedImage` directive provides the following functions:
 * - `provideCloudflareLoader`
 * - `provideCloudinaryLoader`
 * - `provideImageKitLoader`
 * - `provideImgixLoader`
 *
 * If you use a different image provider, you can create a custom loader function as described
 * below.
 *
 * To use a **custom loader**: provide your loader function as a value for the `IMAGE_LOADER` DI
 * token.
 *
 * ```typescript
 * import {IMAGE_LOADER, ImageLoaderConfig} from '@angular/common';
 *
 * // Configure the loader using the `IMAGE_LOADER` token.
 * providers: [
 *   {
 *      provide: IMAGE_LOADER,
 *      useValue: (config: ImageLoaderConfig) => {
 *        return `https://example.com/${config.src}-${config.width}.jpg}`;
 *      }
 *   },
 * ],
 * ```
 *
 * Step 3: update `<img>` tags in templates to use `ngSrc` instead of `src`.
 *
 * ```
 * <img ngSrc="logo.png" width="200" height="100">
 * ```

/**
 * Performs HTTP requests.
 * This service is available as an injectable class, with methods to perform HTTP requests.
 * Each request method has multiple signatures, and the return type varies based on
 * the signature that is called (mainly the values of `observe` and `responseType`).
 *
 * Note that the `responseType` *options* value is a String that identifies the
 * single data type of the response.

 * The value of `responseType` cannot be a union, as the combined signature could imply.

 *
 * @usageNotes
 * Sample HTTP requests for the [Tour of Heroes](/tutorial/tour-of-heroes/toh-pt0) application.
 *
 * ### HTTP Request Example
 *
 * ```
 *  // GET heroes whose name contains search term
 * searchHeroes(term: string): observable<Hero[]>{
 *
 *  const params = new HttpParams({fromString: 'name=term'});
 *    return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});
 * }
 * ```
 *
 * Alternatively, the parameter string can be used without invoking HttpParams
 * by directly joining to the URL.
 * ```
 * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
 * ```
 *
 *
 * ### JSONP Example
 * ```
 * requestJsonp(url, callback = 'callback') {
 *  return this.httpClient.jsonp(this.heroesURL, callback);
 * }
 * ```
 *
 * ### PATCH Example
 * ```
 * // PATCH one of the heroes' name
 * patchHero (id: number, heroName: string): Observable<{}> {
 * const url = `${this.heroesUrl}/${id}`;   // PATCH api/heroes/42
 *  return this.httpClient.patch(url, {name: heroName}, httpOptions)
 *    .pipe(catchError(this.handleError('patchHero')));
 * }
 * ```

 *
 * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
 * the `Injector`. This provides an additional level of type safety.
 *
 * <div class="alert is-helpful">
 *
 * **Important Note**: Ensure that you use the same instance of the `InjectionToken` in both the
 * provider and the injection call. Creating a new instance of `InjectionToken` in different places,
 * even with the same description, will be treated as different tokens by Angular's DI system,
 * leading to a `NullInjectorError`.
 *
 * </div>
 *
 * <code-example format="typescript" language="typescript" path="injection-token/src/main.ts"
 * region="InjectionToken"></code-example>
 *
 * When creating an `InjectionToken`, you can optionally specify a factory function which returns
 * (possibly by creating) a default value of the parameterized type `T`. This sets up the
 * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
 * application's root injector. If the factory function, which takes zero arguments, needs to inject
 * dependencies, it can do so using the [`inject`](api/core/inject) function.
 * As you can see in the Tree-shakable InjectionToken example below.
 *
 * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
 * overrides the above behavior and marks the token as belonging to a particular `@NgModule` (note:
 * this option is now deprecated). As mentioned above, `'root'` is the default value for
 * `providedIn`.

/**

 * - Construction (via the `constructor`) of a class being instantiated by the DI system, such
 * as an `@Injectable` or `@Component`.
 * - In the initializer for fields of such classes.
 * - In the factory function specified for `useFactory` of a `Provider` or an `@Injectable`.
 * - In the `factory` function specified for an `InjectionToken`.
 * - In a stackframe of a function call in a DI context
 *
 * @param token A token that represents a dependency that should be injected.
 * @param flags Optional flags that control how injection is executed.
 * The flags correspond to injection strategies that can be specified with
 * parameter decorators `@Host`, `@Self`, `@SkipSelf`, and `@Optional`.
 * @returns the injected value if operation is successful, `null` otherwise.
 * @throws if called outside of a supported context.
 *
 * @usageNotes
 * In practice the `inject()` calls are allowed in a constructor, a constructor parameter and a
 * field initializer:
 *
 * ```typescript
 * @Injectable({providedIn: 'root'})
 * export class Car {
 *   radio: Radio|undefined;
 *   // OK: field initializer
 *   spareTyre = inject(Tyre);
 *
 *   constructor() {

 *     this.radio = inject(Radio);
 *   }
 * }
 * ```
 *
 * It is also legal to call `inject` from a provider's factory:
 *
 * ```typescript
 * providers: [
 *   {provide: Car, useFactory: () => {
 *     // OK: a class factory
 *     const engine = inject(Engine);
 *     return new Car(engine);
 *   }}
 * ]
 * ```
 *
 * Calls to the `inject()` function outside of the class creation context will result in error. Most
 * notably, calls to `inject()` are disallowed after a class instance was created, in methods
 * (including lifecycle hooks):
 *
 * ```typescript
 * @Component({ ... })
 * export class CarComponent {
 *   ngOnInit() {
 *     // ERROR: too late, the component instance was already created
 *     const engine = inject(Engine);

/**
 * A pattern that recognizes URLs that are safe wrt. XSS in URL navigation

 *
 * This regular expression matches a subset of URLs that will not cause script

 * regular expression matches if:
 * (1) Either a protocol that is not javascript:, and that has valid characters
 *     (alphanumeric or [+-.]).
 * (2) or no protocol.  A protocol must be followed by a colon. The below
 *     allows that by allowing colons only after one of the characters [/?#].
 *     A colon after a hash (#) must be in the fragment.
 *     Otherwise, a colon after a (?) must be in a query.
 *     Otherwise, a colon after a single solidus (/) must be in a path.
 *     Otherwise, a colon after a double solidus (//) must be in the authority
 *     (before port).
 *
 * The pattern disallows &, used in HTML entity declarations before
 * one of the characters in [/?#]. This disallows HTML entities used in the
 * protocol name, which should never happen, e.g. "h&#116;tp" for "http".
 * It also disallows HTML entities in the first path part of a relative path,
 * e.g. "foo&lt;bar/baz".  Our existing escaping functions should not produce
 * that. More importantly, it disallows masking of a colon,
 * e.g. "javascript&#58;...".
 *
 * This regular expression was taken from the Closure sanitization library.

 *
 * @usageNotes
 *
 * The following examples demonstrate how to modify default change-detection behavior
 * to perform explicit detection when needed.
 *
 * ### Use `markForCheck()` with `CheckOnce` strategy
 *
 * The following example sets the `OnPush` change-detection strategy for a component
 * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
 * after an interval.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts"
 * region="mark-for-check"></code-example>
 *
 * ### Detach change detector to limit how often check occurs
 *
 * The following example defines a component with a large list of read-only data
 * that is expected to change constantly, many times per second.
 * To improve performance, we want to check and update the list
 * less often than the changes actually occur. To do that, we detach
 * the component's change detector and perform an explicit local check every five seconds.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
 *
 *
 * ### Reattaching a detached component
 *
 * The following example creates a component displaying live data.
 * The component detaches its change detector from the main change detector tree
 * when the `live` property is set to false, and reattaches it when the property
 * becomes true.

 * <code-example path="core/ts/change_detect/change-detection.ts" region="reattach"></code-example>

/**
 * NOTE: The word `styling` is used interchangeably as style or class styling.
 *
 * This file contains code to link styling instructions together so that they can be replayed in
 * priority order. The file exists because Ivy styling instruction execution order does not match
 * that of the priority order. The purpose of this code is to create a linked list so that the
 * instructions can be traversed in priority order when computing the styles.
 *
 * Assume we are dealing with the following code:
 * ```
 * @Component({
 *   template: `
 *     <my-cmp [style]=" {color: '#001'} "
 *             [style.color]=" #002 "
 *             dir-style-color-1
 *             dir-style-color-2> `
 * })
 * class ExampleComponent {
 *   static ngComp = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#001'});
 *     ɵɵstyleProp('color', '#002');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `[dir-style-color-1]',
 * })
 * class Style1Directive {
 *   @HostBinding('style') style = {color: '#005'};
 *   @HostBinding('style.color') color = '#006';
 *
 *   static ngDir = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#005'});
 *     ɵɵstyleProp('color', '#006');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `[dir-style-color-2]',
 * })
 * class Style2Directive {
 *   @HostBinding('style') style = {color: '#007'};
 *   @HostBinding('style.color') color = '#008';
 *
 *   static ngDir = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#007'});
 *     ɵɵstyleProp('color', '#008');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `my-cmp',
 * })
 * class MyComponent {
 *   @HostBinding('style') style = {color: '#003'};
 *   @HostBinding('style.color') color = '#004';
 *
 *   static ngComp = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#003'});
 *     ɵɵstyleProp('color', '#004');
 *     ...
 *   }
 * }
 * ```
 *
 * The Order of instruction execution is:
 *
 * NOTE: the comment binding location is for illustrative purposes only.
 *
 * ```
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * ```
 *
 * The correct priority order of concatenation is:
 *
 * ```
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * ```
 *
 * What color should be rendered?
 *
 * Once the items are correctly sorted in the list, the answer is simply the last item in the
 * concatenation list which is `#002`.
 *
 * To do so we keep a linked list of all of the bindings which pertain to this element.
 * Notice that the bindings are inserted in the order of execution, but the `TView.data` allows
 * us to traverse them in the order of priority.
 *
 * |Idx|`TView.data`|`LView`          | Notes
 * |---|------------|-----------------|--------------
 * |...|            |                 |

 * |20 |`null`      |`{color: '#003'}`| `ɵɵstyleMap('color', {color: '#003'})`
 * |21 |`0 | 22`    | ...             |
 * |22 |`color`     |`'#004'`         | `ɵɵstyleProp('color', '#004')`
 * |23 |`20 | 24`   | ...             |
 * |24 |`null`      |`{color: '#005'}`| `ɵɵstyleMap('color', {color: '#005'})`
 * |25 |`22 | 26`   | ...             |
 * |26 |`color`     |`'#006'`         | `ɵɵstyleProp('color', '#006')`
 * |27 |`24 | 28`   | ...             |
 * |28 |`null`      |`{color: '#007'}`| `ɵɵstyleMap('color', {color: '#007'})`

 * |31 |`28 | 10`   | ...             |
 *
 * The above data structure allows us to re-concatenate the styling no matter which data binding
 * changes.
 *
 * NOTE: in addition to keeping track of next/previous index the `TView.data` also stores prev/next
 * duplicate bit. The duplicate bit if true says there either is a binding with the same name or
 * there is a map (which may contain the name). This information is useful in knowing if other
 * styles with higher priority need to be searched for overwrites.
 *
 * NOTE: See `should support example in 'tnode_linked_list.ts' documentation` in
 * `tnode_linked_list_spec.ts` for working example.

 * })
 * class MyDir {}
 * ```
 *
 * when `[style.color]="tmplExp"` executes it creates this data structure.
 * ```
 *  ['', 'color', 'color', 'red', 'width', '100px'],
 * ```
 *
 * The reason for this is that the template instruction does not know if there are styling
 * instructions and must assume that there are none and must collect all of the static styling.
 * (both
 * `color' and 'width`)
 *
 * When `'[style.color]': 'dirExp',` executes we need to insert a new data into the linked list.
 * ```
 *  ['', 'color', 'width', '100px'],  // newly inserted
 *  ['', 'color', 'color', 'red', 'width', '100px'], // this is wrong

 * Notice that the template statics is now wrong as it incorrectly contains `width` so we need to
 * update it like so:

 * 2. All `TNodeType.Placeholder` `TNodes` are elements which will be created later by

 * 3. `ɵɵelementStart` instruction will create `TNode`s in the ascending `TNode.index` order. (So a
 *    smaller index `TNode` is guaranteed to be created before a larger one)
 *
 * We use the above three invariants to determine `TNode.insertBeforeIndex`.
 *
 * In an ideal world `TNode.insertBeforeIndex` would always be `TNode.next.index`. However,
 * this will not work because `TNode.next.index` may be larger than `TNode.index` which means that
 * the next node is not yet created and therefore we can't insert in front of it.
 *
 * Rule1: `TNode.insertBeforeIndex = null` if `TNode.next === null` (Initial condition, as we don't
 *        know if there will be further `TNode`s inserted after.)
 * Rule2: If `previousTNode` is created after the `tNode` being inserted, then
 *        `previousTNode.insertBeforeNode = tNode.index` (So when a new `tNode` is added we check
 *        previous to see if we can update its `insertBeforeTNode`)
 *
 * See `TNode.insertBeforeIndex` for more context.
 *

 * These are the data structures that our framework injector profiler will fill with data in order
 * to support DI debugging APIs.
 *
 * resolverToTokenToDependencies: Maps an injector to a Map of tokens to an Array of
 * dependencies. Injector -> Token -> Dependencies This is used to support the
 * getDependenciesFromInjectable API, which takes in an injector and a token and returns it's
 * dependencies.
 *
 * resolverToProviders: Maps a DI resolver (an Injector or a TNode) to the providers configured
 * within it This is used to support the getInjectorProviders API, which takes in an injector and
 * returns the providers that it was configured with. Note that for the element injector case we
 * use the TNode instead of the LView as the DI resolver. This is because the registration of
 * providers happens only once per type of TNode. If an injector is created with an identical TNode,
 * the providers for that injector will not be reconfigured.
 *
 * standaloneInjectorToComponent: Maps the injector of a standalone component to the standalone
 * component that it is associated with. Used in the getInjectorProviders API, specificially in the
 * discovery of import paths for each provider. This is necessary because the imports array of a
 * standalone component is processed and configured in its standalone injector, but exists within
 * the component's definition. Because getInjectorProviders takes in an injector, if that injector
 * is the injector of a standalone component, we need to be able to discover the place where the
 * imports array is located (the component) in order to flatten the imports array within it to
 * discover all of it's providers.
 *
 *
 * All of these data structures are instantiated with WeakMaps. This will ensure that the presence
 * of any object in the keys of these maps does not prevent the garbage collector from collecting
 * those objects. Because of this property of WeakMaps, these data structures will never be the
 * source of a memory leak.
 *
 * An example of this advantage: When components are destroyed, we don't need to do
 * any additional work to remove that component from our mappings.

/**
 * A [DI token](guide/glossary#di-token "DI token definition") that you can use to provide
 * one or more initialization functions.
 *
 * The provided functions are injected at application startup and executed during
 * app initialization. If any of these functions returns a Promise or an Observable, initialization
 * does not complete until the Promise is resolved or the Observable is completed.
 *
 * You can, for example, create a factory function that loads language data
 * or an external configuration, and provide that function to the `APP_INITIALIZER` token.
 * The function is executed during the application bootstrap process,
 * and the needed data is available on startup.
 *
 * @see {@link ApplicationInitStatus}
 *
 * @usageNotes
 *
 * The following example illustrates how to configure a multi-provider using `APP_INITIALIZER` token
 * and a function returning a promise.
 * ### Example with NgModule-based application
 * ```
 *  function initializeApp(): Promise<any> {
 *    return new Promise((resolve, reject) => {
 *      // Do some asynchronous stuff
 *      resolve();
 *    });
 *  }
 *
 *  @NgModule({
 *   imports: [BrowserModule],
 *   declarations: [AppComponent],
 *   bootstrap: [AppComponent],
 *   providers: [{
 *     provide: APP_INITIALIZER,
 *     useFactory: () => initializeApp,
 *     multi: true
 *    }]
 *   })
 *  export class AppModule {}
 * ```
 *
 * ### Example with standalone application
 * ```
 * export function initializeApp(http: HttpClient) {
 *   return (): Promise<any> =>
 *     firstValueFrom(
 *       http
 *         .get("https://someUrl.com/api/user")
 *         .pipe(tap(user => { ... }))
 *     );
 * }
 *
 * bootstrapApplication(App, {
 *   providers: [
 *     provideHttpClient(),
 *     {
 *       provide: APP_INITIALIZER,
 *       useFactory: initializeApp,
 *       multi: true,
 *       deps: [HttpClient],
 *     },
 *   ],
 * });

 * ```
 *
 *
 * It's also possible to configure a multi-provider using `APP_INITIALIZER` token and a function
 * returning an observable, see an example below. Note: the `HttpClient` in this example is used for
 * demo purposes to illustrate how the factory function can work with other providers available
 * through DI.
 *
 * ### Example with NgModule-based application
 * ```
 *  function initializeAppFactory(httpClient: HttpClient): () => Observable<any> {
 *   return () => httpClient.get("https://someUrl.com/api/user")
 *     .pipe(
 *        tap(user => { ... })
 *     );
 *  }
 *
 *  @NgModule({
 *    imports: [BrowserModule, HttpClientModule],
 *    declarations: [AppComponent],
 *    bootstrap: [AppComponent],
 *    providers: [{
 *      provide: APP_INITIALIZER,
 *      useFactory: initializeAppFactory,
 *      deps: [HttpClient],
 *      multi: true
 *    }]
 *  })
 *  export class AppModule {}
 * ```
 *
 * ### Example with standalone application
 * ```
 *  function initializeAppFactory(httpClient: HttpClient): () => Observable<any> {
 *   return () => httpClient.get("https://someUrl.com/api/user")
 *     .pipe(
 *        tap(user => { ... })
 *     );
 *  }
 *
 * bootstrapApplication(App, {
 *   providers: [
 *     provideHttpClient(),
 *     {
 *       provide: APP_INITIALIZER,
 *       useFactory: initializeAppFactory,
 *       multi: true,
 *       deps: [HttpClient],
 *     },
 *   ],

/**
 * A reference to an Angular application running on a page.
 *
 * @usageNotes
 * {@a is-stable-examples}
 * ### isStable examples and caveats
 *
 * Note two important points about `isStable`, demonstrated in the examples below:
 * - the application will never be stable if you start any kind
 * of recurrent asynchronous task when the application starts
 * (for example for a polling process, started with a `setInterval`, a `setTimeout`
 * or using RxJS operators like `interval`);
 * - the `isStable` Observable runs outside of the Angular zone.
 *
 * Let's imagine that you start a recurrent task
 * (here incrementing a counter, using RxJS `interval`),
 * and at the same time subscribe to `isStable`.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *      filter(stable => stable)
 *   ).subscribe(() => console.log('App is stable now');
 *   interval(1000).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, `isStable` will never emit `true`,
 * and the trace "App is stable now" will never get logged.
 *
 * If you want to execute something when the app is stable,
 * you have to wait for the application to be stable
 * before starting your polling process.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     tap(stable => console.log('App is stable now')),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, the trace "App is stable now" will be logged
 * and then the counter starts incrementing every second.
 *
 * Note also that this Observable runs outside of the Angular zone,
 * which means that the code in the subscription
 * to this Observable will not trigger the change detection.
 *
 * Let's imagine that instead of logging the counter value,
 * you update a field of your component
 * and display it in its template.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => this.value = counter);
 * }
 * ```
 * As the `isStable` Observable runs outside the zone,
 * the `value` field will be updated properly,
 * but the template will not be refreshed!
 *
 * You'll have to manually trigger the change detection to update the template.
 *
 * ```
 * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => {
 *     this.value = counter;
 *     cd.detectChanges();
 *   });
 * }
 * ```
 *
 * Or make the subscription callback run inside the zone.
 *
 * ```
 * constructor(appRef: ApplicationRef, zone: NgZone) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => zone.run(() => this.value = counter));
 * }
 * ```

   * Bootstrap a component onto the element identified by its selector or, optionally, to a
   * specified element.
   *
   * @usageNotes
   * ### Bootstrap process
   *
   * When bootstrapping a component, Angular mounts it onto a target DOM element
   * and kicks off automatic change detection. The target DOM element can be
   * provided using the `rootSelectorOrNode` argument.
   *
   * If the target DOM element is not provided, Angular tries to find one on a page
   * using the `selector` of the component that is being bootstrapped
   * (first matched element is used).
   *
   * ### Example
   *
   * Generally, we define the component to bootstrap in the `bootstrap` array of `NgModule`,
   * but it requires us to know the component while writing the application code.
   *
   * Imagine a situation where we have to wait for an API call to decide about the component to
   * bootstrap. We can use the `ngDoBootstrap` hook of the `NgModule` and call this method to
   * dynamically bootstrap a component.
   *
   * {@example core/ts/platform/platform.ts region='componentSelector'}
   *
   * Optionally, a component can be mounted onto a DOM element that does not match the
   * selector of the bootstrapped component.
   *
   * In the following example, we are providing a CSS selector to match the target element.
   *
   * {@example core/ts/platform/platform.ts region='cssSelector'}
   *
   * While in this example, we are providing reference to a DOM node.
   *
   * {@example core/ts/platform/platform.ts region='domNode'}

 *   punctuation symbols).
 * - `local-part` cannot begin or end with a period (`.`).
 * - `local-part` cannot be longer than 64 characters.
 * - `tld` consists of one or more `labels` separated by periods (`.`). For example `localhost` or

 * - A `label` consists of one or more of the allowed characters (alphanumeric, dashes (`-`) and
 *   periods (`.`)).
 * - A `label` cannot begin or end with a dash (`-`) or a period (`.`).
 * - A `label` cannot be longer than 63 characters.
 * - The whole address cannot be longer than 254 characters.
 *
 * ## Implementation background
 *
 * This regexp was ported over from AngularJS (see there for git history):
 * https://github.com/angular/angular.js/blob/c133ef836/src/ng/directive/input.js#L27
 * It is based on the

 * some enhancements to incorporate more RFC rules (such as rules related to domain names and the
 * lengths of different parts of the address). The main differences from the WHATWG version are:
 *   - Disallow `local-part` to begin or end with a period (`.`).
 *   - Disallow `local-part` length to exceed 64 characters.
 *   - Disallow total address length to exceed 254 characters.

  Example:
  // Specify the \`disabled\` property at control creation time:
  form = new FormGroup({
    first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),

  // Using validators arguments
  fc = new FormControl(42, Validators.required, myAsyncValidator);

  // Using AbstractControlOptions
  fc = new FormControl(42, {validators: Validators.required, asyncValidators: myAV});

/**
 * Tracks the value and validity state of a group of `FormControl` instances.
 *
 * A `FormGroup` aggregates the values of each child `FormControl` into one object,
 * with each control name as the key.  It calculates its status by reducing the status values
 * of its children. For example, if one of the controls in a group is invalid, the entire
 * group becomes invalid.
 *
 * `FormGroup` is one of the four fundamental building blocks used to define forms in Angular,
 * along with `FormControl`, `FormArray`, and `FormRecord`.
 *
 * When instantiating a `FormGroup`, pass in a collection of child controls as the first
 * argument. The key for each child registers the name for the control.
 *
 * `FormGroup` is intended for use cases where the keys are known ahead of time.
 * If you need to dynamically add and remove controls, use {@link FormRecord} instead.
 *
 * `FormGroup` accepts an optional type parameter `TControl`, which is an object type with inner
 * control types as values.
 *
 * @usageNotes
 *
 * ### Create a form group with 2 controls
 *
 * ```
 * const form = new FormGroup({
 *   first: new FormControl('Nancy', Validators.minLength(2)),
 *   last: new FormControl('Drew'),
 * });
 *
 * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}
 * console.log(form.status);  // 'VALID'
 * ```
 *
 * ### The type argument, and optional controls
 *
 * `FormGroup` accepts one generic argument, which is an object containing its inner controls.
 * This type will usually be inferred automatically, but you can always specify it explicitly if you
 * wish.
 *
 * If you have controls that are optional (i.e. they can be removed, you can use the `?` in the
 * type):
 *
 * ```
 * const form = new FormGroup<{
 *   first: FormControl<string|null>,
 *   middle?: FormControl<string|null>, // Middle name is optional.
 *   last: FormControl<string|null>,
 * }>({
 *   first: new FormControl('Nancy'),
 *   last: new FormControl('Drew'),
 * });
 * ```
 *
 * ### Create a form group with a group-level validator
 *
 * You include group-level validators as the second arg, or group-level async
 * validators as the third arg. These come in handy when you want to perform validation
 * that considers the value of more than one child control.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('', Validators.minLength(2)),
 *   passwordConfirm: new FormControl('', Validators.minLength(2)),
 * }, passwordMatchValidator);
 *
 *
 * function passwordMatchValidator(g: FormGroup) {
 *    return g.get('password').value === g.get('passwordConfirm').value
 *       ? null : {'mismatch': true};
 * }
 * ```
 *
 * Like `FormControl` instances, you choose to pass in
 * validators and async validators as part of an options object.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('')
 *   passwordConfirm: new FormControl('')
 * }, { validators: passwordMatchValidator, asyncValidators: otherValidator });
 * ```
 *
 * ### Set the updateOn property for all controls in a form group
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * group level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const c = new FormGroup({
 *   one: new FormControl()
 * }, { updateOn: 'blur' });
 * ```
 *
 * ### Using a FormGroup with optional controls
 *
 * It is possible to have optional controls in a FormGroup. An optional control can be removed later
 * using `removeControl`, and can be omitted when calling `reset`. Optional controls must be
 * declared optional in the group's type.
 *
 * ```ts
 * const c = new FormGroup<{one?: FormControl<string>}>({
 *   one: new FormControl('')
 * });
 * ```
 *
 * Notice that `c.value.one` has type `string|null|undefined`. This is because calling `c.reset({})`
 * without providing the optional key `one` will cause it to become `null`.

/**
 * @description
 * Creates a top-level `FormGroup` instance and binds it to a form
 * to track aggregate form value and validation status.
 *
 * As soon as you import the `FormsModule`, this directive becomes active by default on
 * all `<form>` tags.  You don't need to add a special selector.
 *
 * You optionally export the directive into a local template variable using `ngForm` as the key
 * (ex: `#myForm="ngForm"`). This is optional, but useful.  Many properties from the underlying
 * `FormGroup` instance are duplicated on the directive itself, so a reference to it
 * gives you access to the aggregate value and validity status of the form, as well as
 * user interaction properties like `dirty` and `touched`.
 *
 * To register child controls with the form, use `NgModel` with a `name`
 * attribute. You may use `NgModelGroup` to create sub-groups within the form.
 *
 * If necessary, listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event emits the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * To import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, add the `ngNoForm` and the `<form>`
 * tags won't create an `NgForm` directive. In reactive forms, using `ngNoForm` is
 * unnecessary because the `<form>` tags are inert. In that case, you would
 * refrain from using the `formGroup` directive.
 *
 * @usageNotes
 *
 * ### Listening for form submission
 *
 * The following example shows how to capture the form values from the "ngSubmit" event.
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Setting the update options
 *
 * The following example shows you how to change the "updateOn" option from its default using
 * ngFormOptions.
 *
 * ```html
 * <form [ngFormOptions]="{updateOn: 'blur'}">
 *    <input name="one" ngModel>  <!-- this ngModel will update on blur -->
 * </form>
 * ```
 *
 * ### Native DOM validation UI
 *
 * In order to prevent the native DOM form validation UI from interfering with Angular's form
 * validation, Angular automatically adds the `novalidate` attribute on any `<form>` whenever
 * `FormModule` or `ReactiveFormModule` are imported into the application.
 * If you want to explicitly enable native DOM validation UI with Angular forms, you can add the
 * `ngNativeValidate` attribute to the `<form>` element:
 *
 * ```html
 * <form ngNativeValidate>
 *   ...
 * </form>
 * ```

 * @ngModule FormsModule
 * @publicApi

/**
 * @description
 * Creates a `FormControl` instance from a [domain
 * model](https://en.wikipedia.org/wiki/Domain_model) and binds it to a form control element.
 *
 * The `FormControl` instance tracks the value, user interaction, and
 * validation status of the control and keeps the view synced with the model. If used
 * within a parent form, the directive also registers itself with the form as a child
 * control.
 *
 * This directive is used by itself or as part of a larger form. Use the
 * `ngModel` selector to activate it.
 *
 * It accepts a domain model as an optional `Input`. If you have a one-way binding
 * to `ngModel` with `[]` syntax, changing the domain model's value in the component
 * class sets the value in the view. If you have a two-way binding with `[()]` syntax
 * (also known as 'banana-in-a-box syntax'), the value in the UI always syncs back to
 * the domain model in your class.
 *
 * To inspect the properties of the associated `FormControl` (like the validity state),
 * export the directive into a local template variable using `ngModel` as the key (ex:
 * `#myVar="ngModel"`). You can then access the control using the directive's `control` property.
 * However, the most commonly used properties (like `valid` and `dirty`) also exist on the control
 * for direct access. See a full list of properties directly available in
 * `AbstractControlDirective`.
 *
 * @see {@link RadioControlValueAccessor}
 * @see {@link SelectControlValueAccessor}
 *
 * @usageNotes
 *
 * ### Using ngModel on a standalone control
 *
 * The following examples show a simple standalone control using `ngModel`:
 *
 * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}
 *
 * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute
 * so that the control can be registered with the parent form under that name.
 *
 * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,
 * as the parent form syncs the value for you. You access its properties by exporting it into a
 * local template variable using `ngForm` such as (`#f="ngForm"`). Use the variable where
 * needed on form submission.
 *
 * If you do need to populate initial values into your form, using a one-way binding for
 * `ngModel` tends to be sufficient as long as you use the exported form's value rather
 * than the domain model's value on submit.
 *
 * ### Using ngModel within a form
 *
 * The following example shows controls using `ngModel` within a form:
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Using a standalone ngModel within a group
 *
 * The following example shows you how to use a standalone ngModel control
 * within a form. This controls the display of the form, but doesn't contain form data.
 *
 * ```html
 * <form>
 *   <input name="login" ngModel placeholder="Login">
 *   <input type="checkbox" ngModel [ngModelOptions]="{standalone: true}"> Show more options?
 * </form>
 * <!-- form value: {login: ''} -->
 * ```
 *
 * ### Setting the ngModel `name` attribute through options
 *
 * The following example shows you an alternate way to set the name attribute. Here,
 * an attribute identified as name is used within a custom form control component. To still be able
 * to specify the NgModel's name, you must specify it using the `ngModelOptions` input instead.
 *
 * ```html
 * <form>
 *   <my-custom-form-control name="Nancy" ngModel [ngModelOptions]="{name: 'user'}">
 *   </my-custom-form-control>
 * </form>
 * <!-- form value: {user: ''} -->
 * ```

 *
 * ```ts
 *   this.form.get('name.first');

 * @description
 * The `ControlValueAccessor` for writing select control values and listening to select control
 * changes. The value accessor is used by the `FormControlDirective`, `FormControlName`, and
 * `NgModel` directives.
 *
 * @usageNotes
 *
 * ### Using select controls in a reactive form
 *
 * The following examples show how to use a select control in a reactive form.
 *
 * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
 *
 * ### Using select controls in a template-driven form
 *
 * To use a select in a template-driven form, simply add an `ngModel` and a `name`
 * attribute to the main `<select>` tag.
 *
 * {@example forms/ts/selectControl/select_control_example.ts region='Component'}
 *
 * ### Customizing option selection
 *
 * Angular uses object identity to select option. It's possible for the identities of items
 * to change while the data does not. This can happen, for example, if the items are produced
 * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the
 * second response will produce objects with different identities.
 *
 * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
 * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
 * If `compareWith` is given, Angular selects option by the return value of the function.
 *
 * ```ts
 * const selectedCountriesControl = new FormControl();
 * ```
 *
 * ```
 * <select [compareWith]="compareFn"  [formControl]="selectedCountriesControl">
 *     <option *ngFor="let country of countries" [ngValue]="country">
 *         {{country.name}}
 *     </option>
 * </select>
 *
 * compareFn(c1: Country, c2: Country): boolean {
 *     return c1 && c2 ? c1.id === c2.id : c1 === c2;
 * }
 * ```
 *
 * **Note:** We listen to the 'change' event because 'input' events aren't fired
 * for selects in IE, see:
 * https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/input_event#browser_compatibility
 *

/**
 * Tracks the value and validity state of an array of `FormControl`,
 * `FormGroup` or `FormArray` instances.
 *
 * A `FormArray` aggregates the values of each child `FormControl` into an array.
 * It calculates its status by reducing the status values of its children. For example, if one of
 * the controls in a `FormArray` is invalid, the entire array becomes invalid.
 *
 * `FormArray` accepts one generic argument, which is the type of the controls inside.
 * If you need a heterogenous array, use {@link UntypedFormArray}.
 *
 * `FormArray` is one of the four fundamental building blocks used to define forms in Angular,
 * along with `FormControl`, `FormGroup`, and `FormRecord`.
 *
 * @usageNotes
 *
 * ### Create an array of form controls
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * ### Create a form array with array-level validators
 *
 * You include array-level validators and async validators. These come in handy
 * when you want to perform validation that considers the value of more than one child
 * control.
 *
 * The two types of validators are passed in separately as the second and third arg
 * respectively, or together as part of an options object.
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy'),
 *   new FormControl('Drew')
 * ], {validators: myValidator, asyncValidators: myAsyncValidator});
 * ```
 *
 * ### Set the updateOn property for all controls in a form array
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * array level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const arr = new FormArray([
 *    new FormControl()
 * ], {updateOn: 'blur'});
 * ```
 *
 * ### Adding or removing controls from a form array
 *
 * To change the controls in the array, use the `push`, `insert`, `removeAt` or `clear` methods
 * in `FormArray` itself. These methods ensure the controls are properly tracked in the
 * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate
 * the `FormArray` directly, as that result in strange and unexpected behavior such
 * as broken change detection.

// Notes on the accessibility pattern used for `mat-optgroup`.
// The option group has two different "modes": regular and inert. The regular mode uses the
// recommended a11y pattern which has `role="group"` on the group element with `aria-labelledby`
// pointing to the label. This works for `mat-select`, but it seems to hit a bug for autocomplete
// under VoiceOver where the group doesn't get read out at all. The bug appears to be that if
// there's __any__ a11y-related attribute on the group (e.g. `role` or `aria-labelledby`),
// VoiceOver on Safari won't read it out.
// We've introduced the `inert` mode as a workaround. Under this mode, all a11y attributes are
// removed from the group, and we get the screen reader to read out the group label by mirroring it
// inside an invisible element in the option. This is sub-optimal, because the screen reader will
// repeat the group label on each navigation, whereas the default pattern only reads the group when
// the user enters a new group. The following alternate approaches were considered:
// 1. Reading out the group label using the `LiveAnnouncer` solves the problem, but we can't control
//    when the text will be read out so sometimes it comes in too late or never if the user
//    navigates quickly.
// 2. `<mat-option aria-describedby="groupLabel"` - This works on Safari, but VoiceOver in Chrome
//    won't read out the description at all.
// 3. `<mat-option aria-labelledby="optionLabel groupLabel"` - This works on Chrome, but Safari
//     doesn't read out the text at all. Furthermore, on
// Counter for unique group ids.

This rather complicates the\n    setup because it would require every form-field control to explicitly set `aria-labelledby`.\n    This is because the `<label>` itself contains more than the actual label (e.g. prefix, suffix\n    or other projected content), and screen readers could potentially read out undesired content.\n    Excluding elements from being printed out requires them to be marked with `aria-hidden`, or\n    the form control is set to a scoped element for the label (using `aria-labelledby`). Both of\n    these options seem to complicate the setup because we know exactly what content is rendered\n    as part of the label, and we don't want to spend resources on walking through projected content\n    to set `aria-hidden`.

 * Bootstraps an instance of an Angular application and renders a standalone component as the

 *
 * @usageNotes
 * The root component passed into this function *must* be a standalone one (should have the
 * `standalone: true` flag in the `@Component` decorator config).
 *
 * ```typescript
 * @Component({
 *   standalone: true,
 *   template: 'Hello world!'
 * })
 * class RootComponent {}
 *
 * const appRef: ApplicationRef = await bootstrapApplication(RootComponent);
 * ```
 *
 * You can add the list of providers that should be available in the application injector by
 * specifying the `providers` field in an object passed as the second argument:
 *
 * ```typescript
 * await bootstrapApplication(RootComponent, {
 *   providers: [
 *     {provide: BACKEND_URL, useValue: 'https://yourdomain.com/api'}
 *   ]
 * });
 * ```
 *
 * The `importProvidersFrom` helper method can be used to collect all providers from any
 * existing NgModule (and transitively from all NgModules that it imports):
 *
 * ```typescript
 * await bootstrapApplication(RootComponent, {
 *   providers: [
 *     importProvidersFrom(SomeNgModule)
 *   ]
 * });
 * ```
 *
 * Note: the `bootstrapApplication` method doesn't include [Testability](api/core/Testability) by
 * default. You can add [Testability](api/core/Testability) by getting the list of necessary
 * providers using `provideProtractorTestingSupport()` function and adding them into the `providers`
 * array, for example:
 *
 * ```typescript
 * import {provideProtractorTestingSupport} from '@angular/platform-browser';
 *
 * await bootstrapApplication(RootComponent, {providers: [provideProtractorTestingSupport()]});
 * ```
 *
 * @param rootComponent A reference to a standalone component that should be rendered.

/**
 * DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
 * values to be safe to use in the different DOM contexts.
 *
 * For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
 * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
 * the website.
 *
 * In specific situations, it might be necessary to disable sanitization, for example if the
 * application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
 * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
 * methods, and then binding to that value from the template.
 *
 * These situations should be very rare, and extraordinary care must be taken to avoid creating a
 * Cross Site Scripting (XSS) security bug!
 *
 * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
 * close as possible to the source of the value, to make it easy to verify no security bug is
 * created by its use.
 *
 * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
 * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
 * code. The sanitizer leaves safe values intact.
 *
 * @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
 * sanitization for the value passed in. Carefully check and audit all values and code paths going
 * into this call. Make sure any user data is appropriately escaped for this security context.
 * For more detail, see the [Security Guide](https://g.co/ng/security).

/**

 * Acts as a placeholder that Angular dynamically fills based on the current router state.
 *
 * Each outlet can have a unique name, determined by the optional `name` attribute.
 * The name cannot be set or changed dynamically. If not set, default value is "primary".
 *
 * ```
 * <router-outlet></router-outlet>
 * <router-outlet name='left'></router-outlet>
 * <router-outlet name='right'></router-outlet>
 * ```
 *
 * Named outlets can be the targets of secondary routes.
 * The `Route` object for a secondary route has an `outlet` property to identify the target outlet:
 *
 * `{path: <base-path>, component: <component>, outlet: <target_outlet_name>}`
 *
 * Using named outlets and secondary routes, you can target multiple outlets in
 * the same `RouterLink` directive.
 *
 * The router keeps track of separate branches in a navigation tree for each named outlet and
 * generates a representation of that tree in the URL.
 * The URL for a secondary route uses the following syntax to specify both the primary and secondary
 * routes at the same time:
 *
 * `http://base-path/primary-route-path(outlet-name:route-path)`
 *
 * A router outlet emits an activate event when a new component is instantiated,
 * deactivate event when a component is destroyed.
 * An attached event emits when the `RouteReuseStrategy` instructs the outlet to reattach the
 * subtree, and the detached event emits when the `RouteReuseStrategy` instructs the outlet to
 * detach the subtree.
 *

/**
 * @description
 *
 * When applied to an element in a template, makes that element a link
 * that initiates navigation to a route. Navigation opens one or more routed components
 * in one or more `<router-outlet>` locations on the page.
 *
 * Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
 * the following creates a static link to the route:
 * `<a routerLink="/user/bob">link to user component</a>`
 *
 * You can use dynamic values to generate the link.
 * For a dynamic link, pass an array of path segments,
 * followed by the params for each segment.
 * For example, `['/team', teamId, 'user', userName, {details: true}]`
 * generates a link to `/team/11/user/bob;details=true`.
 *
 * Multiple static segments can be merged into one term and combined with dynamic segments.
 * For example, `['/team/11/user', userName, {details: true}]`
 *
 * The input that you provide to the link is treated as a delta to the current URL.
 * For instance, suppose the current URL is `/user/(box//aux:team)`.
 * The link `<a [routerLink]="['/user/jim']">Jim</a>` creates the URL
 * `/user/(jim//aux:team)`.
 * See {@link Router#createUrlTree} for more information.
 *
 * @usageNotes
 *
 * You can use absolute or relative paths in a link, set query parameters,
 * control how parameters are handled, and keep a history of navigation states.
 *
 * ### Relative link paths
 *
 * The first segment name can be prepended with `/`, `./`, or `../`.
 * * If the first segment begins with `/`, the router looks up the route from the root of the
 *   app.
 * * If the first segment begins with `./`, or doesn't begin with a slash, the router
 *   looks in the children of the current activated route.
 * * If the first segment begins with `../`, the router goes up one level in the route tree.
 *
 * ### Setting and handling query params and fragments
 *
 * The following link adds a query parameter and a fragment to the generated URL:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
 *   link to user component
 * </a>
 * ```
 * By default, the directive constructs the new URL using the given query parameters.
 * The example generates the link: `/user/bob?debug=true#education`.
 *
 * You can instruct the directive to handle query parameters differently
 * by specifying the `queryParamsHandling` option in the link.
 * Allowed values are:
 *
 *  - `'merge'`: Merge the given `queryParams` into the current query params.
 *  - `'preserve'`: Preserve the current query params.
 *
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
 *   link to user component
 * </a>
 * ```
 *
 * See {@link UrlCreationOptions#queryParamsHandling}.
 *
 * ### Preserving navigation history
 *
 * You can provide a `state` value to be persisted to the browser's
 * [`History.state` property](https://developer.mozilla.org/en-US/docs/Web/API/History#Properties).
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
 *   link to user component
 * </a>
 * ```
 *
 * Use {@link Router#getCurrentNavigation} to retrieve a saved
 * navigation-state value. For example, to capture the `tracingId` during the `NavigationStart`
 * event:
 *
 * ```
 * // Get NavigationStart events
 * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
 *   const navigation = router.getCurrentNavigation();
 *   tracingService.trace({id: navigation.extras.state.tracingId});
 * });
 * ```

/**
 *
 * @description
 *
 * Tracks whether the linked route of an element is currently active, and allows you
 * to specify one or more CSS classes to add to the element when the linked route
 * is active.
 *
 * Use this directive to create a visual distinction for elements associated with an active route.
 * For example, the following code highlights the word "Bob" when the router
 * activates the associated route:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
 * ```
 *
 * Whenever the URL is either '/user' or '/user/bob', the "active-link" class is
 * added to the anchor tag. If the URL changes, the class is removed.
 *
 * You can set more than one class using a space-separated string or an array.
 * For example:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
 * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
 * ```
 *
 * To add the classes only when the URL matches the link exactly, add the option `exact: true`:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
 * true}">Bob</a>
 * ```
 *
 * To directly check the `isActive` status of the link, assign the `RouterLinkActive`
 * instance to a template variable.
 * For example, the following checks the status without assigning any CSS classes:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
 *   Bob {{ rla.isActive ? '(already open)' : ''}}
 * </a>
 * ```
 *
 * You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
 * For example, the following sets the active-link class on the `<div>`  parent tag
 * when the URL is either '/user/jim' or '/user/bob'.
 *
 * ```
 * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
 *   <a routerLink="/user/jim">Jim</a>
 *   <a routerLink="/user/bob">Bob</a>
 * </div>
 * ```
 *
 * The `RouterLinkActive` directive can also be used to set the aria-current attribute
 * to provide an alternative distinction for active elements to visually impaired users.
 *
 * For example, the following code adds the 'active' class to the Home Page link when it is
 * indeed active and in such case also sets its aria-current attribute to 'page':
 *
 * ```
 * <a routerLink="/" routerLinkActive="active" ariaCurrentWhenActive="page">Home Page</a>
 * ```
