-/**
- * Projects each source value to an Observable which is merged in the output
- * Observable, emitting values only from the most recently projected Observable.
- *
- * <span class="informal">Maps each value to an Observable, then flattens all of
- * these inner Observables.</span>
- *
- * ![](switchMap.png)
- *
- * Returns an Observable that emits items based on applying a function that you
- * supply to each item emitted by the source Observable, where that function
- * returns an (so-called "inner") Observable. Each time it observes one of these
- * inner Observables, the output Observable begins emitting the items emitted by
- * that inner Observable. When a new inner Observable is emitted, `switchMap`
- * stops emitting items from the earlier-emitted inner Observable and begins
- * emitting items from the new one. It continues to behave like this for
- * subsequent inner Observables.
- *
- * ## Example
- * Rerun an interval Observable on every click event
- * ```javascript
- * import { fromEvent, interval } from 'rxjs';
- * import { switchMap } from 'rxjs/operators';
- *
- * const clicks = fromEvent(document, 'click');
- * const result = clicks.pipe(switchMap((ev) => interval(1000)));
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link concatMap}
- * @see {@link exhaustMap}
- * @see {@link mergeMap}
- * @see {@link switchAll}
- * @see {@link switchMapTo}
- *
- * @param {function(value: T, ?index: number): ObservableInput} project A function
- * that, when applied to an item emitted by the source Observable, returns an
- * Observable.
- * @return {Observable} An Observable that emits the result of applying the
- * projection function (and the optional deprecated `resultSelector`) to each item
- * emitted by the source Observable and taking only the values from the most recently
- * projected inner Observable.
- * @method switchMap
- * @owner Observable
