What is throttling?
Imagine you are scrolling down a long page for 3 seconds and you have bindWithDelay running with a timeout of 1000ms. By default, your event will only fire a second after you have completely finished scrolling. If you have the optional throttling on, it will fire once per second during the scrolling – a total of 3 times instead of 1.
