Is your React app slow or laggy?

In this video, we fix some of the most common performance mistakes developers make in React — including unnecessary useEffect runs, expensive calculations, and too many API calls.

You’ll learn how to:

* control useEffect properly
* avoid unnecessary re-renders
* optimize performance using useMemo
* reduce API calls using debouncing

These are real-world issues that can impact your app’s performance and are commonly discussed in interviews.

If you're a beginner, college student, or preparing for React interviews, this video will help you write cleaner and more efficient code.

Let me know in the comments — which mistake have you made before?
