+ * Emits only the last `count` values emitted by the source Observable.

+ * <span class="informal">Remembers the latest `count` values, then emits those
+ * only when the source completes.</span>
+ *
+ * ![](takeLast.png)
+ *
+ * `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
+ * Take the last 3 values of an Observable with many values
+ * ```ts
+ * import { range } from 'rxjs';
+ * import { takeLast } from 'rxjs/operators';
+ *
+ * const many = range(1, 100);
+ * const lastThree = many.pipe(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
+ * @owner Observable
