What are the best practices for optimizing React performance?

To optimize React performance, consider techniques like code splitting, memoization, and using the React Profiler.

Can you explain code splitting and how to implement it?

Code splitting allows you to split your code into smaller chunks, loading them on demand. You can implement it using React.lazy and Suspense.

What is memoization and how does it help with performance?

Memoization is a technique to cache the results of expensive function calls. In React, you can use React.memo for components and useMemo for values.

How can I use the React Profiler to identify performance issues?

The React Profiler helps you measure the performance of your components. You can wrap your components with <Profiler> and analyze the results in the React DevTools.
