🚀Boost Your React Performance with useMemo and useCallback🚀

Optimizing React applications is all about knowing the right tools—and two of the most powerful ones in your toolkit are useMemo and useCallback. These hooks can help you avoid unnecessary re-renders and recalculations, making your app faster and smoother.

What You’ll Learn:

• When and why to use useMemo
• How useCallback can save you from performance pitfalls
• Code examples to get you started

Here’s a sneak peek 👇:

useMemo: Simplify Complex Calculations
useMemo lets you memoize the result of a function. It recalculates only when dependencies change, saving computation time.

const squaredValue = useMemo(() => {
  return count * count;
}, [count]);

useCallback: Memoize Functions Like a Pro
useCallback ensures your callback functions are not recreated on every render, preventing unnecessary re-renders in child components.

const handleChange = useCallback((e) => {
  setText(e.target.value);
}, []);
