- * Emits the values emitted by the source Observable until a `notifier`
- * Observable emits a value.
- *
- * <span class="informal">Lets values pass until a second Observable,
- * `notifier`, emits a value. Then, it completes.</span>
- *
- * 
- *
- * `takeUntil` subscribes and begins mirroring the source Observable. It also
- * monitors a second Observable, `notifier` that you provide. If the `notifier`
- * emits a value, the output Observable stops mirroring the source Observable
- * and completes. If the `notifier` doesn't emit any value and completes
- * then `takeUntil` will pass all values.
- *
- * ## Example
- *
- * Tick every second until the first click happens
- *
- * ```ts
- * import { interval, fromEvent, takeUntil } from 'rxjs';
- *
- * const source = interval(1000);
- * const clicks = fromEvent(document, 'click');
- * const result = source.pipe(takeUntil(clicks));
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link take}
- * @see {@link takeLast}
- * @see {@link takeWhile}
- * @see {@link skip}
- *
- * @param notifier The `ObservableInput` whose first emitted value will cause the output
- * Observable of `takeUntil` to stop emitting values from the source Observable.
- * @return A function that returns an Observable that emits the values from the
- * source Observable until `notifier` emits its first value.
