+ *
+ * `takeLast` returns an Observable that emits at most the last `count` values
+ * emitted by the source Observable. If the source emits fewer than `count`
+ * values then all of its values are emitted. This operator must wait until the
+ * `complete` notification emission from the source in order to emit the `next`
+ * values on the output Observable, because otherwise it is impossible to know
+ * whether or not more values will be emitted on the source. For this reason,
+ * all values are emitted synchronously, followed by the complete notification.
+ *
+ * @example <caption>Take the last 3 values of an Observable with many values</caption>
+ * var many = Rx.Observable.range(1, 100);
+ * var lastThree = many.takeLast(3);
+ * lastThree.subscribe(x => console.log(x));
+ *
+ * @see {@link take}
+ * @see {@link takeUntil}
+ * @see {@link takeWhile}
+ * @see {@link skip}
+ *
+ * @throws {ArgumentOutOfRangeError} When using `takeLast(i)`, it delivers an
+ * ArgumentOutOrRangeError to the Observer's `error` callback if `i < 0`.
+ *
+ * @param {number} count The maximum number of values to emit from the end of
+ * the sequence of values emitted by the source Observable.
+ * @return {Observable<T>} An Observable that emits at most the last count
+ * values emitted by the source Observable.
+ * @method takeLast
