What is Debouncing in JavaScript?

Debouncing is a programming technique that ensures a function is executed only after a certain period of inactivity. It helps optimize event handling and prevents unnecessary function calls.

Why should you use Debouncing?

Debouncing improves performance by reducing the number of times a function is triggered. It is especially useful in scenarios like search boxes, window resizing, and scroll events.

What is an example of Debouncing in real-world applications?

A common example of debouncing is in search input fields. Instead of sending a request to the server on every keystroke, debouncing waits until the user stops typing for a short duration before making the request.

⏳ What is Debouncing?

Debouncing: Limits rapid event triggers by executing a function only after the last event in a series, with a delay.
Like waiting to confirm an event before taking action!

Rapid Events: Every keystroke triggers a search, overwhelming the server.

⏳

Debouncing: Wait for typing to pause, then trigger the search!

😌

Result: Fewer server calls, smoother performance, and better user experience!
