+ * Projects each source value to the same Observable which is flattened multiple
+ * times with {@link switchMap} in the output Observable.
+ *
+ * <span class="informal">It's like {@link switchMap}, but maps each value
+ * always to the same inner Observable.</span>
+ *
+ * ![](switchMapTo.png)
+ *
+ * Maps each source value to the given Observable `innerObservable` regardless
+ * of the source value, and then flattens those resulting Observables into one
+ * single Observable, which is the output Observable. The output Observables
+ * emits values only from the most recently emitted instance of
+ * `innerObservable`.
+ *
+ * ## Example
+ *
+ * Restart an interval Observable on every click event
+ *
+ * ```ts
+ * import { fromEvent, switchMapTo, interval } from 'rxjs';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const result = clicks.pipe(switchMapTo(interval(1000)));
+ * result.subscribe(x => console.log(x));
+ * ```
+ *
+ * @see {@link concatMapTo}
+ * @see {@link switchAll}
+ * @see {@link switchMap}
+ * @see {@link mergeMapTo}
+ *
+ * @param innerObservable An `ObservableInput` to replace each value from the
+ * source Observable.
+ * @return A function that returns an Observable that emits items from the
+ * given `innerObservable` (and optionally transformed through the deprecated
+ * `resultSelector`) every time a value is emitted on the source Observable,
+ * and taking only the values from the most recently projected inner
+ * Observable.
+ * @deprecated Will be removed in v9. Use {@link switchMap} instead: `switchMap(() => result)`
