What is Debouncing?

Debouncing is a programming practice that ensures a specific task is only executed after a set amount of time has passed since the last time it was triggered. Essentially, it waits for a "pause" in activity before performing an action, preventing a function from running too many times in quick succession.

The Elevator Analogy

Imagine you are standing in an elevator in a busy office building. As you step in, the door starts to close. Suddenly, a coworker runs up and taps the "open door" button. The door reopens, resetting the timer. This happens again and again—every time someone arrives, the door's automatic closing process is canceled and restarted. The elevator only actually begins its journey once there has been a lull in arrivals for, say, five seconds. That pause is your debounce window.
