What is Debouncing in JS?

Debouncing in JavaScript delays the execution of a function until a certain time has passed since the last event, preventing wasteful repeated calls. This is useful for input typing, such as search boxes, where each keypress is an event. To implement debouncing, use a timer that resets with each new event and only executes the function when the delay time has passed with no new events. A simple code example is provided to understand the concept.
