|

|
* 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');
