Sometimes React re-renders components even when it’s not needed—this can slow down your app. That’s where React.memo helps!
? What is React.memo?
It’s a higher-order component that prevents re-rendering if props haven’t changed. Great for optimizing functional components.
? How to Use:
const MyComponent = React.memo(function MyComponent(props) {
return <div>{props.value}</div>;
});
? Why It Matters:
Saves performance in large or complex UIs
Useful when passing the same props repeatedly
? Note:
It works best with pure components—those that render the same output for the same props.
? Final Thought: React.memo helps you write faster, smarter React apps by avoiding unnecessary work!
