- * Buffers the source Observable values until the size hits the maximum
- * `bufferSize` given.
- *
- * <span class="informal">Collects values from the past as an array, and emits
- * that array only when its size reaches `bufferSize`.</span>
- *
- * 
- *
- * Buffers a number of values from the source Observable by `bufferSize` then
- * emits the buffer and clears it, and starts a new buffer each
- * `startBufferEvery` values. If `startBufferEvery` is not provided or is
- * `null`, then new buffers are started immediately at the start of the source
- * and when each buffer closes and is emitted.
- *
- * ## Examples
- *
- * Emit the last two click events as an array
- *
- * ```ts
- * import { fromEvent, bufferCount } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const buffered = clicks.pipe(bufferCount(2));
- * buffered.subscribe(x => console.log(x));
- * ```
- *
- * On every click, emit the last two click events as an array
- *
- * ```ts
- * import { fromEvent, bufferCount } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const buffered = clicks.pipe(bufferCount(2, 1));
- * buffered.subscribe(x => console.log(x));
- * ```

- * @see {@link buffer}
- * @see {@link bufferTime}
- * @see {@link bufferToggle}
- * @see {@link bufferWhen}
- * @see {@link pairwise}
- * @see {@link windowCount}
- *
- * @param bufferSize The maximum size of the buffer emitted.
- * @param startBufferEvery Interval at which to start a new buffer.
- * For example if `startBufferEvery` is `2`, then a new buffer will be started
- * on every other value from the source. A new buffer is started at the
- * beginning of the source by default.
- * @return A function that returns an Observable of arrays of buffered values.
