/**
 * 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

 *
 * The provided functions are injected at application startup and executed during

 *
 * You can, for example, create a factory function that loads language data

 * The function is executed during the application bootstrap process,
 * and the needed data is available on startup.

 *
 * 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
 * ```ts
 *  function initializeApp(): Promise<any> {
 *    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 => { ... }))
 *   );
 * }
 *
 * @NgModule({
 *   imports: [BrowserModule, HttpClientModule],
 *   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,
