-/**
- * 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
