Understanding Debounce in JavaScript

Debounce is a powerful technique used in JavaScript to improve performance by limiting how often a function is executed. It's especially useful in events like onChange, onScroll, or window resizing. Instead of executing a function every time the event fires, debounce delays the execution until a certain amount of time has passed without the event being triggered again. This reduces redundant executions and improves responsiveness. For example, in a search input field, debounce ensures that API calls are only made when the user has paused typing, rather than on every keystroke.
