  	 * Emits a value from the source Observable, then ignores subsequent source
  	 * values for a duration determined by another Observable, then repeats this

  	 *
  	 * `throttle` emits the source Observable values on the output Observable
  	 * when its internal timer is disabled, and ignores source values when the timer
  	 * is enabled. Initially, the timer is disabled. As soon as the first source
  	 * value arrives, it is forwarded to the output Observable, and then the timer
  	 * is enabled by calling the `durationSelector` function with the source value,
  	 * which returns the "duration" Observable. When the duration Observable emits a
  	 * value or completes, the timer is disabled, and this process repeats for the
  	 * next source value.
  	 *
  	 * @example <caption>Emit clicks at a rate of at most one click per second</caption>
  	 * var clicks = Rx.Observable.fromEvent(document, 'click');
  	 * var result = clicks.throttle(ev => Rx.Observable.interval(1000));
  	 * result.subscribe(x => console.log(x));
  	 *

  	 * @param {function(value: T): Observable|Promise} durationSelector A function
  	 * that receives a value from the source Observable, for computing the silencing
  	 * duration for each source value, returned as an Observable or a Promise.
  	 * @return {Observable<T>} An Observable that performs the throttle operation to
  	 * limit the rate of emissions from the source.
