React useCallback Hook – Optimize Functional Components

In this video by Mohit Decodes, you'll learn about the useCallback hook in React. This hook helps you memoize functions to prevent unnecessary re-creations during re-renders — especially useful when passing callbacks to child components.

📌 Topics Covered:
What is useCallback in React?
Difference between useMemo and useCallback.
When and why to use useCallback.
Practical use-case with component performance demo.
Common interview questions and real-world scenarios.

💡 Perfect for intermediate React developers who want to level up their performance optimization game.
