- * <span class="informal">It's like {@link throttleTime}, but the silencing

- *
- * ![](throttle.svg)
- *
- * `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, the timer is disabled, and this process repeats for the
- * next source value.
- *
- * ## Example
- *
- * Emit clicks at a rate of at most one click per second
- *
- * ```ts
- * import { fromEvent, throttle, interval } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const result = clicks.pipe(throttle(() => interval(1000)));
- *
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link audit}
- * @see {@link debounce}
- * @see {@link delayWhen}
- * @see {@link sample}
- * @see {@link throttleTime}
- *
- * @param durationSelector A function that receives a value from the source
- * Observable, for computing the silencing duration for each source value,
- * returned as an `ObservableInput`.
- * @param config A configuration object to define `leading` and `trailing`
- * behavior. Defaults to `{ leading: true, trailing: false }`.
- * @return A function that returns an Observable that performs the throttle
- * operation to limit the rate of emissions from the source.
