+ * Emits the most recently emitted value from the source Observable whenever
+ * another Observable, the `notifier`, emits.
+ *
+ * <span class="informal">It's like {@link sampleTime}, but samples whenever
+ * the `notifier` Observable emits something.</span>
+ *
+ * ![](sample.png)
+ *
+ * Whenever the `notifier` Observable emits a value or completes, `sample`
+ * looks at the source Observable and emits whichever value it has most recently
+ * emitted since the previous sampling, unless the source has not emitted
+ * anything since the previous sampling. The `notifier` is subscribed to as soon
+ * as the output Observable is subscribed.
+ *
+ * ## Example
+ * On every click, sample the most recent "seconds" timer
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { sample } from 'rxjs/operators';
+ *
+ * const seconds = interval(1000);
+ * const clicks = fromEvent(document, 'click');
+ * const result = seconds.pipe(sample(clicks));
+ * result.subscribe(x => console.log(x));
+ * ```
+ *
+ * @see {@link audit}
+ * @see {@link debounce}
+ * @see {@link sampleTime}
+ * @see {@link throttle}
+ *
+ * @param {Observable<any>} notifier The Observable to use for sampling the
+ * source Observable.
+ * @return {Observable<T>} An Observable that emits the results of sampling the
+ * values emitted by the source Observable whenever the notifier Observable
+ * emits value or completes.
+ * @method sample
+ * @owner Observable
