Frontend Optimisation Techniques: Part 1 — Debouncing 🚀
Debouncing is a powerful optimization technique used in JavaScript and frontend development to control how frequently a function executes, especially during events that trigger repeatedly in a short span of time such as typing, scrolling, resizing, or button clicks. Instead of running a function every single time an event occurs, debouncing delays the ex*****on until a specified amount of time has passed without any new trigger. This improves performance, reduces unnecessary API calls, enhances user experience, and prevents applications from becoming slow or overloaded. A common real-world example is a search bar where the API request is sent only after the user stops typing for a moment, rather than after every keystroke. In this reel, we break down how debouncing works internally, why it is essential in modern web applications, and how developers can implement it efficiently using JavaScript to build faster and more optimized interfaces.
