|

*
|
||||
* `take` returns an Observable that emits only the first `count` values emitted
|
||||
* by the source Observable. If the source emits fewer than `count` values then
|
||||
* all of its values are emitted. After that, it completes, regardless if the
|
||||
* source completes.
|
||||
*
|
||||
* @example <caption>Take the first 5 seconds of an infinite 1-second interval Observable</caption>
|
||||
* var interval = Rx.Observable.interval(1000);
|
||||
* var five = interval.take(5);
|
||||
* five.subscribe(x => console.log(x));

* @see {@link takeLast}
|
||||
* @see {@link takeUntil}
|
||||
* @see {@link takeWhile}
|
||||
* @see {@link skip}
|
||||
*
|
||||
* @throws {ArgumentOutOfRangeError} When using `take(i)`, it delivers an
|
||||
* ArgumentOutOrRangeError to the Observer's `error` callback if `i < 0`.
|
||||
*
|
||||
* @param {number} count The maximum number of `next` values to emit.
|
||||
* @return {Observable<T>} An Observable that emits only the first `count`
|
||||
* values emitted by the source Observable, or all of the values from the source
|
||||
* if the source emits fewer than `count` values.
