What are the best practices for optimizing React applications?

To optimize React applications, 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 use React.lazy and Suspense for this.

What is memoization and why is it important?

Memoization is a technique to cache the results of expensive function calls. In React, it helps prevent unnecessary re-renders.

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

The React Profiler helps you measure the performance of your components. You can use it to track rendering times and identify bottlenecks.
