When should I use React.memo?

When should I use React.memo in my React applications?

You should use React.memo when you want to prevent unnecessary re-renders of a component that receives the same props.

Can you give me an example of when it would be beneficial?

Sure! If you have a component that renders a list of items and it receives props that don't change often, wrapping it in React.memo can improve performance.

Are there any downsides to using React.memo?

Yes, if the props are complex objects, React.memo might not provide a performance boost due to shallow comparison. It's best for simple props.

How do I implement React.memo in my code?

You can implement it by wrapping your functional component with React.memo like this: const MyComponent = React.memo((props) => { ... }).
