+ * `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.
