intervalExponential

intervalExponential works similiarly to interval except that it doubles the delay between emissions every time.

intervalExponential is especially useful for periodic polls that are reset whenever user activity is detected:

fromEvent(document, 'mousemove').pipe(

    // There could be many mousemoves, we'd want to sample only
    // with certain frequency
    sampleTime(LOAD_INTERVAL_MS),

    // Start immediately
    startWith(null),

    // Resetting exponential interval
    switchMapTo(intervalExponential({initialInterval: LOAD_INTERVAL_MS, maxInterval: MAX_INTERVAL_MS})),
  );
