When should I use class components instead of functional components?

Class components are useful when you need to manage local state or lifecycle methods. Functional components are simpler and preferred for most cases.

Can you give me an example of when to use a class component?

Sure! If you need to implement complex lifecycle methods like componentDidMount or manage state, a class component is ideal.

What about hooks? Do they change the need for class components?

Yes, hooks allow functional components to manage state and side effects, reducing the need for class components in many scenarios.

Are there any performance differences between the two?

Generally, functional components with hooks can be more performant due to optimizations like React.memo, but it depends on the use case.
