What are the best practices for rendering in React?

Some best practices include using functional components, memoization, and avoiding unnecessary re-renders.

Can you explain how memoization works in React?

Memoization in React helps optimize performance by caching the results of expensive function calls and returning the cached result when the same inputs occur again.

What is the difference between class components and functional components?

Class components are ES6 classes that can hold state and lifecycle methods, while functional components are simpler and can use hooks for state and side effects.

How can I prevent unnecessary re-renders in my application?

You can use React.memo for functional components, PureComponent for class components, and optimize state management.
