What is debouncing in JavaScript?

Debouncing in JavaScript is a programming technique used to ensure that a function is only executed after a specified amount of time has passed since it was last invoked. This is particularly useful for optimizing performance in scenarios where a function may be called multiple times in rapid succession, such as during window resizing, scrolling, or keystroke events. By using debouncing, we can limit the number of times a function is executed, thus improving application efficiency and responsiveness.
