+ * Emits a value from the source Observable only after a particular time span
+ * determined by another Observable has passed without another source emission.
+ *
+ * <span class="informal">It's like {@link debounceTime}, but the time span of
+ * emission silence is determined by a second Observable.</span>

+ *
+ * `debounce` delays values emitted by the source Observable, but drops previous
+ * pending delayed emissions if a new value arrives on the source Observable.
+ * This operator keeps track of the most recent value from the source
+ * Observable, and spawns a duration Observable by calling the
+ * `durationSelector` function. The value is emitted only when the duration
+ * Observable emits a value or completes, and if no other value was emitted on
+ * the source Observable since the duration Observable was spawned. If a new
+ * value appears before the duration Observable emits, the previous value will
+ * be dropped and will not be emitted on the output Observable.
+ *
+ * Like {@link debounceTime}, this is a rate-limiting operator, and also a
+ * delay-like operator since output emissions do not necessarily occur at the
+ * same time as they did on the source Observable.
+ *
+ * @example <caption>Emit the most recent click after a burst of clicks</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.debounce(() => Rx.Observable.interval(1000));
+ * result.subscribe(x => console.log(x));
+ *
+ * @see {@link audit}
+ * @see {@link debounceTime}
+ * @see {@link delayWhen}
+ * @see {@link throttle}
+ *
+ * @param {function(value: T): SubscribableOrPromise} durationSelector A function
+ * that receives a value from the source Observable, for computing the timeout
+ * duration for each source value, returned as an Observable or a Promise.
+ * @return {Observable} An Observable that delays the emissions of the source
+ * Observable by the specified duration Observable returned by
+ * `durationSelector`, and may drop some values if they occur too frequently.
+ * @method debounce
+ * @owner Observable
