How do I use React.memo in my React application?

React.memo is a higher-order component that helps optimize performance by memoizing functional components. It prevents unnecessary re-renders when the props haven't changed.

Can you give me an example of how to implement it?

Sure! You can wrap your functional component with React.memo like this:

const MyComponent = React.memo((props) => {
  // component logic
});

What are the benefits of using React.memo?

The main benefit is improved performance by reducing the number of re-renders. It’s especially useful for components that receive the same props frequently.

Are there any downsides to using it?

Yes, if the component is lightweight, the overhead of memoization might outweigh the performance benefits. It's best used for complex components.
