| * 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. |
| * |
| * @example <caption>Emit the last two click events as an array</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var buffered = clicks.bufferCount(2); |
| * buffered.subscribe(x => console.log(x)); |
| * |
| * @example <caption>On every click, emit the last two click events as an array</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var buffered = clicks.bufferCount(2, 1); |
| * buffered.subscribe(x => console.log(x)); |
