 * ![](take.png)
 *
 * `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
 * Take the first 5 seconds of an infinite 1-second interval Observable
 * ```ts
 * import { interval } from 'rxjs';
 * import { take } from 'rxjs/operators';
 *
 * const intervalCount = interval(1000);
 * const takeFive = intervalCount.pipe(take(5));
 * takeFive.subscribe(x => console.log(x));
 *
 * // Logs:
 * // 0
 * // 1
 * // 2
 * // 3
 * // 4
 * ```
 *
 * @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.
 * @method take
 * @owner Observable
