* `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.
|
|
*
|
|
* @example <caption>Tick every second until the first click happens</caption>
|
|
* var interval = Rx.Observable.interval(1000);
|
|
* var clicks = Rx.Observable.fromEvent(document, 'click');
|
|
* var result = interval.takeUntil(clicks);
|
|
* result.subscribe(x => console.log(x));
