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

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

Functional components are simpler and use hooks for state and lifecycle methods, while class components use 'this' and have more boilerplate.

Can you explain when to use one over the other?

Use functional components for simpler UI and when you want to leverage hooks. Class components are useful for complex state management.

Are there performance differences between them?

Functional components can be more performant due to less overhead, especially with React's optimizations like memoization.

What about the learning curve for beginners?

Functional components are generally easier for beginners to grasp, especially with the introduction of hooks, making them more approachable.
