 *
 * **Important Note**: Ensure that you use the same instance of the `InjectionToken` in both the

 * leading to a `NullInjectorError`.
 *
 * </div>
 *
 * {@example injection-token/src/main.ts region='InjectionToken'}
 *
 * 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

/**
 * Stores DOM operations which need to be applied to update DOM render tree due to changes in
 * expressions.
 *
 * The basic idea is that `i18nExp` OpCodes capture expression changes and update a change
 * mask bit. (Bit 1 for expression 1, bit 2 for expression 2 etc..., bit 32 for expression 32 and
 * higher.) The OpCodes then compare its own change mask against the expression change mask to
 * determine if the OpCodes should execute.
 *
 * NOTE: 32nd bit is special as it says 32nd or higher. This way if we have more than 32 bindings
 * the code still works, but with lower efficiency. (it is unlikely that a translation would have
 * more than 32 bindings.)
 *
 * These OpCodes can be used by both the i18n block as well as ICU sub-block.
 *
 * ## Example
 *
 * Assume
 * ```ts
 *   if (rf & RenderFlags.Update) {
 *    i18nExp(ctx.exp1); // If changed set mask bit 1
 *    i18nExp(ctx.exp2); // If changed set mask bit 2
 *    i18nExp(ctx.exp3); // If changed set mask bit 3
 *    i18nExp(ctx.exp4); // If changed set mask bit 4
 *    i18nApply(0);            // Apply all changes by executing the OpCodes.
 *  }
 * ```
 * We can assume that each call to `i18nExp` sets an internal `changeMask` bit depending on the
 * index of `i18nExp`.
 *
 * ### OpCodes
 * ```ts
 * <I18nUpdateOpCodes>[
 *   // The following OpCodes represent: `<div i18n-title="pre{{exp1}}in{{exp2}}post">`
 *   // If `changeMask & 0b11`
 *   //        has changed then execute update OpCodes.
 *   //        has NOT changed then skip `8` values and start processing next OpCodes.
 *   0b11, 8,
 *   // Concatenate `newValue = 'pre'+lView[bindIndex-4]+'in'+lView[bindIndex-3]+'post';`.
 *   'pre', -4, 'in', -3, 'post',
 *   // Update attribute: `elementAttribute(1, 'title', sanitizerFn(newValue));`
 *   1 << SHIFT_REF | Attr, 'title', sanitizerFn,
 *
 *   // The following OpCodes represent: `<div i18n>Hello {{exp3}}!">`
 *   // If `changeMask & 0b100`
 *   //        has changed then execute update OpCodes.
 *   //        has NOT changed then skip `4` values and start processing next OpCodes.
 *   0b100, 4,
 *   // Concatenate `newValue = 'Hello ' + lView[bindIndex -2] + '!';`.
 *   'Hello ', -2, '!',
 *   // Update text: `lView[1].textContent = newValue;`
 *   1 << SHIFT_REF | Text,
 *

 * Store the static values for the styling binding.
 *
 * The `TStylingStatic` is just `KeyValueArray` where key `""` (stored at location 0) contains the
 * `TStylingKey` (stored at location 1). In other words this wraps the `TStylingKey` such that the
 * `""` contains the wrapped value.
 *
 * When instructions are resolving styling they may need to look forward or backwards in the linked
 * list to resolve the value. For this reason we have to make sure that he linked list also contains
 * the static values. However the list only has space for one item per styling instruction. For this
 * reason we store the static values here as part of the `TStylingKey`. This means that the
 * resolution function when looking for a value needs to first look at the binding value, and than
 * at `TStylingKey` (if it exists).
 *
 * Imagine we have:
 *
 * ```angular-ts
 * <div class="TEMPLATE" my-dir>
 *
 * @Directive({
 *   host: {
 *     class: 'DIR',
 *     '[class.dynamic]': 'exp' // ɵɵclassProp('dynamic', ctx.exp);
 *   }
 * })
 * ```
 *
 * In the above case the linked list will contain one item:
 *
 * ```ts
 *   // assume binding location: 10 for `ɵɵclassProp('dynamic', ctx.exp);`
 *   tData[10] = <TStylingStatic>[
 *     '': 'dynamic', // This is the wrapped value of `TStylingKey`
 *     'DIR': true,   // This is the default static value of directive binding.
 *   ];
 *   tData[10 + 1] = 0; // We don't have prev/next.
 *
 *   lView[10] = undefined;     // assume `ctx.exp` is `undefined`
 *   lView[10 + 1] = undefined; // Just normalized `lView[10]`
 * ```
 *
 * So when the function is resolving styling value, it first needs to look into the linked list
 * (there is none) and than into the static `TStylingStatic` too see if there is a default value for
 * `dynamic` (there is not). Therefore it is safe to remove it.
 *
 * If setting `true` case:
 * ```ts
 *   lView[10] = true;     // assume `ctx.exp` is `true`
 *   lView[10 + 1] = true; // Just normalized `lView[10]`
 * ```
 * So when the function is resolving styling value, it first needs to look into the linked list
 * (there is none) and than into `TNode.residualClass` (TNode.residualStyle) which contains
 * ```ts
 *   tNode.residualClass = [
 *     'TEMPLATE': true,
 *   ];
 * ```
 *
 * This means that it is safe to add class.

     * See: `DECLARATION_VIEW` which points to the actual `LView` where it was declared, whereas
     * `DECLARATION_COMPONENT_VIEW` points to the component which may not be same as
     * `DECLARATION_VIEW`.
     *
     * Example:
     * ```html
     * <#VIEW #myComp>
     *  <div *ngIf="true">
     *   <ng-template #myTmpl>...</ng-template>
     *  </div>
     * </#VIEW>
     * ```
     * In the above case `DECLARATION_VIEW` for `myTmpl` points to the `LView` of `ngIf` whereas
     * `DECLARATION_COMPONENT_VIEW` points to `LView` of the `myComp` which owns the template.
     *
     * The reason for this is that all embedded views are always check-always whereas the component
     * view can be check-always or on-push. When we have a transplanted view it is important to
     * determine if we have transplanted a view from check-always declaration to on-push insertion
     * point. In such a case the transplanted view needs to be added to the `LContainer` in the
     * declared `LView` and CD during the declared view CD (in addition to the CD at the insertion
     * point.) (Any transplanted views which are intra Component are of no interest because the CD
     * strategy of declaration and insertion will always be the same, because it is the same
     * component.)
     *
     * Queries already track moved views in `LView[DECLARATION_LCONTAINER]` and
     * `LContainer[MOVED_VIEWS]`. However the queries also track `LView`s which moved within the same
     * component `LView`. Transplanted views are a subset of moved views, and we use
     * `DECLARATION_COMPONENT_VIEW` to differentiate them. As in this example.
     *
     * Example showing intra component `LView` movement.
     * ```html
     * <#VIEW #myComp>
     *   <div *ngIf="condition; then thenBlock else elseBlock"></div>
     *   <ng-template #thenBlock>Content to render when condition is true.</ng-template>
     *   <ng-template #elseBlock>Content to render when condition is false.</ng-template>
     * </#VIEW>
     * ```
     * The `thenBlock` and `elseBlock` is moved but not transplanted.
     *
     * Example showing inter component `LView` movement (transplanted view).
     * ```html
     * <#VIEW #myComp>
     *   <ng-template #myTmpl>...</ng-template>
     *   <insertion-component [template]="myTmpl"></insertion-component>
     * </#VIEW>
     * ```
     * In the above example `myTmpl` is passed into a different component. If `insertion-component`
     * instantiates `myTmpl` and `insertion-component` is on-push then the `LContainer` needs to be
     * marked as containing transplanted views and those views need to be CD as part of the
     * declaration CD.
     *
     *
     * When change detection runs, it iterates over `[MOVED_VIEWS]` and CDs any child `LView`s where
     * the `DECLARATION_COMPONENT_VIEW` of the current component and the child `LView` does not match
     * (it has been transplanted across components.)
     *
     * Note: `[DECLARATION_COMPONENT_VIEW]` points to itself if the LView is a component view (the
     *       simplest / most common case).
     *

/**
 * Stores a set of OpCodes to process `HostBindingsFunction` associated with a current view.
 *
 * In order to invoke `HostBindingsFunction` we need:
 * 1. 'elementIdx`: Index to the element associated with the `HostBindingsFunction`.
 * 2. 'directiveIdx`: Index to the directive associated with the `HostBindingsFunction`. (This will
 *    become the context for the `HostBindingsFunction` invocation.)
 * 3. `bindingRootIdx`: Location where the bindings for the `HostBindingsFunction` start. Internally
 *    `HostBindingsFunction` binding indexes start from `0` so we need to add `bindingRootIdx` to
 *    it.
 * 4. `HostBindingsFunction`: A host binding function to execute.
 *
 * The above information needs to be encoded into the `HostBindingOpCodes` in an efficient manner.
 *
 * 1. `elementIdx` is encoded into the `HostBindingOpCodes` as `~elementIdx` (so a negative number);
 * 2. `directiveIdx`
 * 3. `bindingRootIdx`
 * 4. `HostBindingsFunction` is passed in as is.
 *
 * The `HostBindingOpCodes` array contains:
 * - negative number to select the element index.
 * - followed by 1 or more of:
 *    - a number to select the directive index
 *    - a number to select the bindingRoot index
 *    - and a function to invoke.
 *
 * ## Example
 *
 * ```ts
 * const hostBindingOpCodes = [
 *   ~30,                               // Select element 30
 *   40, 45, MyDir.ɵdir.hostBindings    // Invoke host bindings on MyDir on element 30;
 *                                      // directiveIdx = 40; bindingRootIdx = 45;
 *   50, 55, OtherDir.ɵdir.hostBindings // Invoke host bindings on OtherDire on element 30
 *                                      // directiveIdx = 50; bindingRootIdx = 55;
 * ]
 * ```
 *
 * ## Pseudocode
 * ```ts
 * const hostBindingOpCodes = tView.hostBindingOpCodes;
 * if (hostBindingOpCodes === null) return;
 * for (let i = 0; i < hostBindingOpCodes.length; i++) {
 *   const opCode = hostBindingOpCodes[i] as number;
 *   if (opCode < 0) {
 *     // Negative numbers are element indexes.
 *     setSelectedIndex(~opCode);
 *   } else {
 *     // Positive numbers are NumberTuple which store bindingRootIndex and directiveIndex.
 *     const directiveIdx = opCode;
 *     const bindingRootIndx = hostBindingOpCodes[++i] as number;
 *     const hostBindingFn = hostBindingOpCodes[++i] as HostBindingsFunction<any>;
 *     setBindingRootForHostBindings(bindingRootIndx, directiveIdx);

     *
     * ### Declaring directives
     *
     * In order to make a directive available to other components in your application, you should do
     * one of the following:
     *  - either mark the directive as [standalone](guide/components/importing),
     *  - or declare it in an NgModule by adding it to the `declarations` and `exports` fields.
     *
     * ** Marking a directive as standalone **
     *
     * You can add the `standalone: true` flag to the Directive decorator metadata to declare it as
     * [standalone](guide/components/importing):
     *
     * ```ts
     * @Directive({
     *   standalone: true,
     *   selector: 'my-directive',
     * })
     * class MyDirective {}
     * ```
     *
     * When marking a directive as standalone, please make sure that the directive is not already
     * declared in an NgModule.
     *
     *
     * ** Declaring a directive in an NgModule **
     *
     * Another approach is to declare a directive in an NgModule:
     *
     * ```ts
     * @Directive({
     *   selector: 'my-directive',
     * })
     * class MyDirective {}
     *
     * @NgModule({
     *   declarations: [MyDirective, SomeComponent],
     *   exports: [MyDirective], // making it available outside of this module
     * })
     * class SomeNgModule {}
     * ```
     *
     * When declaring a directive in an NgModule, please make sure that:
     *  - the directive is declared in exactly one NgModule.
     *  - the directive is not standalone.
     *  - you do not re-declare a directive imported from another module.
     *  - the directive is included into the `exports` field as well if you want this directive to be
     *    accessible for components outside of the NgModule.

     *
     * @usageNotes
     *
     * ### Setting component inputs
     *
     * The following example creates a component with two data-bound properties,
     * specified by the `inputs` value.
     *
     * {@example core/ts/metadata/directives.ts region='component-input'}
     *
     *
     * ### Setting component outputs
     *
     * The following example shows two event emitters that emit on an interval. One
     * emits an output every second, while the other emits every five seconds.
     *
     * {@example core/ts/metadata/directives.ts region='component-output-interval'}
     *
     * ### Injecting a class with a view provider
     *
     * The following simple example injects a class into a component
     * using the view provider specified in component metadata:
     *
     * ```ts
     * class Greeter {
     *    greet(name:string) {
     *      return 'Hello ' + name + '!';
     *    }
     * }
     *
     * @Directive({
     *   selector: 'needs-greeter'
     * })
     * class NeedsGreeter {
     *   greeter:Greeter;
     *
     *   constructor(greeter:Greeter) {
     *     this.greeter = greeter;
     *   }
     * }
     *
     * @Component({
     *   selector: 'greet',
     *   viewProviders: [
     *     Greeter
     *   ],
     *   template: `<needs-greeter></needs-greeter>`
     * })
     * class HelloWorld {
     * }
     *
     * ```
     *
     * ### Preserving whitespace
     *
     * Removing whitespace can greatly reduce AOT-generated code size and speed up view creation.
     * As of Angular 6, the default for `preserveWhitespaces` is false (whitespace is removed).
     * To change the default setting for all components in your application, set
     * the `preserveWhitespaces` option of the AOT compiler.
     *
     * By default, the AOT compiler removes whitespace characters as follows:
     * * Trims all whitespaces at the beginning and the end of a template.
     * * Removes whitespace-only text nodes. For example,
     *
     * ```html
     * <button>Action 1</button>  <button>Action 2</button>
     * ```
     *
     * becomes:
     *
     * ```html
     * <button>Action 1</button><button>Action 2</button>
     * ```
     *
     * * Replaces a series of whitespace characters in text nodes with a single space.

     * where whitespace characters are significant.
     *
     * Note that these transformations can influence DOM nodes layout, although impact
     * should be minimal.
     *
     * You can override the default behavior to preserve whitespace characters
     * in certain fragments of a template. For example, you can exclude an entire
     * DOM sub-tree by using the `ngPreserveWhitespaces` attribute:
     *
     * ```html
     * <div ngPreserveWhitespaces>
     *     whitespaces are preserved here
     *     <span>    and here </span>
     * </div>
     * ```
     *
     * You can force a single space to be preserved in a text node by using `&ngsp;`,
     * which is replaced with a space character by Angular's template
     * compiler:
     *
     * ```html
     * <a>Spaces</a>&ngsp;<a>between</a>&ngsp;<a>links.</a>
     * <!-- compiled to be equivalent to:
     *  <a>Spaces</a> <a>between</a> <a>links.</a>  -->
     * ```
     *
     * Note that sequences of `&ngsp;` are still collapsed to just one space character when
     * the `preserveWhitespaces` option is set to `false`.
     *
     * ```html
     * <a>before</a>&ngsp;&ngsp;&ngsp;<a>after</a>
     * <!-- compiled to be equivalent to:
     *  <a>before</a> <a>after</a> -->
     * ```
     *
     * To preserve sequences of whitespace characters, use the
     * `ngPreserveWhitespaces` attribute.

 *
 * - be [idempotent](https://en.wikipedia.org/wiki/Idempotence) (be without side effects, and always
 * return the same value for a given input)

 *
 * @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.
 *
 * {@example core/ts/change_detect/change-detection.ts region='mark-for-check'}
 *
 * ### 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.
 *
 * {@example core/ts/change_detect/change-detection.ts region='detach'}
 *
 *
 * ### 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

/**
 * A reference to an Angular application running on a page.
 *
 * @usageNotes
 * ### 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`.
 *
 * ```ts
 * 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.
 *
 * ```ts
 * 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.
 *
 * ```ts
 * 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.
 *
 * ```ts
 * 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.
 *
 * ```ts
 * constructor(appRef: ApplicationRef, zone: NgZone) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => zone.run(() => this.value = counter));
 * }
 * ```

     *
     * When bootstrapping a component, Angular mounts it onto a target DOM element

     * Optionally, a component can be mounted onto a DOM element that does not match the

 *    const http = inject(HttpClient);
 *    return firstValueFrom(
 *      http
 *        .get("https://someUrl.com/api/user")
 *        .pipe(tap(user => { ... }))
 *    );
 *  }
 *
 *  @NgModule({
 *   imports: [BrowserModule],
 *   declarations: [AppComponent],
 *   bootstrap: [AppComponent],
 *   providers: [{
 *     provide: APP_INITIALIZER,
 *     useValue: initializeApp,
 *     multi: true,
 *    }]
 *   })
 *  export class AppModule {}
 * ```
 *
 * ### Example with standalone application
 * ```ts
 * function initializeApp() {
 *   const http = inject(HttpClient);
 *   return firstValueFrom(
 *     http
 *       .get("https://someUrl.com/api/user")
 *       .pipe(tap(user => { ... }))
 *   );
 * }
 *
 * bootstrapApplication(App, {
 *   providers: [
 *     provideHttpClient(),
 *     {
 *       provide: APP_INITIALIZER,
 *       useValue: initializeApp,
 *       multi: true,
 *     },
 *   ],
 * });

 * ```
 *
 *
 * 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
 * ```ts
 * function initializeApp() {
 *   const http = inject(HttpClient);
 *   return firstValueFrom(
 *     http
 *       .get("https://someUrl.com/api/user")
 *       .pipe(tap(user => { ... }))
 *   );

 * Creates a `ComponentRef` instance based on provided component type and a set of options.

 * The example below demonstrates how the `createComponent` function can be used
 * to create an instance of a ComponentRef dynamically and attach it to an ApplicationRef,
 * so that it gets included into change detection cycles.
 *
 * Note: the example uses standalone components, but the function can also be used for
 * non-standalone components (declared in an NgModule) as well.
 *
 * ```angular-ts
 * @Component({
 *   standalone: true,
 *   template: `Hello {{ name }}!`
 * })
 * class HelloComponent {
 *   name = 'Angular';
 * }
 *
 * @Component({
 *   standalone: true,
 *   template: `<div id="hello-component-host"></div>`
 * })
 * class RootComponent {}
 *
 * // Bootstrap an application.
 * const applicationRef = await bootstrapApplication(RootComponent);
 *
 * // Locate a DOM node that would be used as a host.
 * const hostElement = document.getElementById('hello-component-host');
 *
 * // Get an `EnvironmentInjector` instance from the `ApplicationRef`.
 * const environmentInjector = applicationRef.injector;
 *
 * // We can now create a `ComponentRef` instance.
 * const componentRef = createComponent(HelloComponent, {hostElement, environmentInjector});
 *
 * // Last step is to register the newly created ref using the `ApplicationRef` instance
 * // to include the component view into change detection cycles.
 * applicationRef.attachView(componentRef.hostView);
 * componentRef.changeDetectorRef.detectChanges();
 * ```
 *
 * @param component Component class reference.
 * @param options Set of options to use:
 *  * `environmentInjector`: An `EnvironmentInjector` instance to be used for the component.
 *  * `hostElement` (optional): A DOM node that should act as a host node for the component. If not
 * provided, Angular creates one based on the tag name used in the component selector (and falls
 * back to using `div` if selector doesn't have tag name info).
 *  * `elementInjector` (optional): An `ElementInjector` instance, see additional info about it
 * [here](guide/di/hierarchical-dependency-injection#elementinjector).
 *  * `projectableNodes` (optional): A list of DOM nodes that should be projected through
 * [`<ng-content>`](api/core/ng-content) of the new component instance, e.g.,
 * `[[element1, element2]]`: projects `element1` and `element2` into the same `<ng-content>`.
 * `[[element1, element2], [element3]]`: projects `element1` and `element2` into one `<ng-content>`,
