Debounce JS programming challenge
Debounce
Debouncing is a way of ensuring that a function is only called once when fired multiple times in a short period. Almost all keyboards have some form of built in debouncing since the keys will hit the sensor quite a few times per keystroke. For keyboards, the delay is somewhere around 50ms.
In Javascript, debouncing is important for rapidly firing events, such as text input. Instead of firing a keydown event and processing input data on every keypress, you fire the event once after no more keypresses are detected in a certain amount of time.
