React Functional Components vs Class Components

What are the main differences between functional and class components in React?

Functional components are simpler and easier to read, while class components offer more features like lifecycle methods.

When should I use functional components over class components?

Use functional components when you don't need lifecycle methods or state management, as they are more efficient.

Can functional components manage state?

Yes, with the introduction of hooks like useState and useEffect, functional components can manage state and side effects.

Are there any performance differences between the two?

Functional components generally have better performance due to less overhead, especially with React's optimizations.
