When should I use classes instead of components in React?

When should I use classes instead of functional components in React?

You should use class components when you need to manage local state or lifecycle methods. Functional components are simpler and preferred for most cases.

What are the advantages of using functional components?

Functional components are easier to read and test, and they can use hooks for state and lifecycle features, making them more versatile.

Are there any performance differences between the two?

Generally, functional components can be more performant due to optimizations like React.memo, but the difference is often negligible for most applications.

Can I convert a class component to a functional component?

Yes, you can convert a class component to a functional component by using hooks to manage state and lifecycle methods.

What should I consider when deciding between the two?

Consider the complexity of the component, the need for state management, and whether you want to leverage hooks.
