| * Skip the last `count` values emitted by the source Observable. |
| * |
| * ![](skipLast.png) |
| * |
| * `skipLast` returns an Observable that accumulates a queue with a length |
| * enough to store the first `count` values. As more values are received, |
| * values are taken from the front of the queue and produced on the result |
| * sequence. This causes values to be delayed. |
| * |
| * ## Example |
| * Skip the last 2 values of an Observable with many values |
| * ```ts |
| * import { range } from 'rxjs'; |
| * import { skipLast } from 'rxjs/operators'; |
| * |
| * const many = range(1, 5); |
| * const skipLastTwo = many.pipe(skipLast(2)); |
| * skipLastTwo.subscribe(x => console.log(x)); |
| * |
| * // Results in: |
| * // 1 2 3 |
| * ``` |
| * |
| * @see {@link skip} |
| * @see {@link skipUntil} |
| * @see {@link skipWhile} |
| * @see {@link take} |
| * |
| * @throws {ArgumentOutOfRangeError} When using `skipLast(i)`, it throws |
| * ArgumentOutOrRangeError if `i < 0`. |
| * |
| * @param {number} count Number of elements to skip from the end of the source Observable. |
| * @returns {Observable<T>} An Observable that skips the last count values |
| * emitted by the source Observable. |
| * @method skipLast |
| * @owner Observable |
