This snippet is useful when applied to events that occur many times such as resize and scroll, particularly when the callback does heavy processing. It throttles the calls to the callback by only calling in to the callback if the event has not occurred again in the last 300ms. This technique is called ‘debouncing’.

Three years have passed since I posted my first article on the blog. Time for a retrospective!
