/**
 * A function optionally passed into the `NgForOf` directive to customize how `NgForOf` uniquely
 * identifies items in an iterable.
 *
 * `NgForOf` needs to uniquely identify items in the iterable to correctly perform DOM updates
 * when items in the iterable are reordered, new items are added, or existing items are removed.
 *
 *
 * In all of these scenarios it is usually desirable to only update the DOM elements associated
 * with the items affected by the change. This behavior is important to:
 *
 * - preserve any DOM-specific UI state (like cursor position, focus, text selection) when the
 *   iterable is modified
 * - enable animation of item addition, removal, and iterable reordering
 * - preserve the value of the `<select>` element when nested `<option>` elements are dynamically
 *   populated using `NgForOf` and the bound iterable is updated
 *
 * A common use for custom `trackBy` functions is when the model that `NgForOf` iterates over
 * contains a property with a unique identifier. For example, given a model:
 *
 * ```ts
 * class User {
 *   id: number;
 *   name: string;
 *   ...
 * }
 * ```
 * a custom `trackBy` function could look like the following:
 * ```ts
 * function userTrackBy(index, user) {
 *   return user.id;
 * }
 * ```
 *
 * A custom `trackBy` function must have several properties:
 *
 * - be [idempotent](https://en.wikipedia.org/wiki/Idempotence) (be without side effects, and always
 * return the same value for a given input)
 * - return unique value for all unique inputs
 * - be fast

 *    const http = inject(HttpClient);
 *    return firstValueFrom(
 *      http
 *        .get("https://someUrl.com/api/user")

 *    );
 *  }

 *   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 => { ... }))
 *   );
 * }

 * class HelloComponent {
 *   name = 'Angular';
 * }
 *
 * @Component({
 *   template: `<div id="hello-component-host"></div>`

 * // Locate a DOM node that would be used as a host.
 * const hostElement = document.getElementById('hello-component-host');

 * const environmentInjector = applicationRef.injector;
 *
 * // We can now create a `ComponentRef` instance.

 * // to include the component view into change detection cycles.

 *  * `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>`,
 * and `element3` into a separate `<ng-content>`.
