+/**
+ * Buffers the source Observable values, using a factory function of closing
+ * Observables to determine when to close, emit, and reset the buffer.
+ *
+ * <span class="informal">Collects values from the past as an array. When it
+ * starts collecting values, it calls a function that returns an Observable that
+ * tells when to close the buffer and restart collecting.</span>
+ *
+ * ![](bufferWhen.png)
+ *
+ * Opens a buffer immediately, then closes the buffer when the observable
+ * returned by calling `closingSelector` function emits a value. When it closes
+ * the buffer, it immediately opens a new buffer and repeats the process.
+ *
+ * ## Example
+ *
+ * Emit an array of the last clicks every [1-5] random seconds
+ *
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { bufferWhen } from 'rxjs/operators';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const buffered = clicks.pipe(bufferWhen(() =>
+ *   interval(1000 + Math.random() * 4000)
+ * ));
+ * buffered.subscribe(x => console.log(x));
+ * ```

+ * @param {function(): Observable} closingSelector A function that takes no
+ * arguments and returns an Observable that signals buffer closure.
+ * @return {Observable<T[]>} An observable of arrays of buffered values.
