How can I optimize my React app for better performance?

There are several strategies you can use to optimize your React app, such as code splitting, lazy loading, and memoization. Would you like to dive into any specific technique?

What is code splitting and how do I implement it?

Code splitting is a technique that allows you to split your code into smaller chunks, which can be loaded on demand. You can implement it using React's React.lazy and Suspense.

Can you give me an example of using React.lazy?

Sure! You can use it like this: const LazyComponent = React.lazy(() => import('./LazyComponent')); Then wrap it in a <Suspense> component to handle loading states.

What about memoization? How does it help?

Memoization helps to optimize performance by caching the results of expensive function calls and returning the cached result when the same inputs occur again. In React, you can use React.memo for components and useMemo for values.
