| * `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. |
