How do class-based and functional components compare in performance?

How do class-based and functional components compare in performance?

Class-based components tend to have more overhead due to their lifecycle methods, while functional components can be more efficient.

What about the impact of hooks on functional components?

Hooks allow functional components to manage state and side effects, making them more powerful and often more performant.

Are there specific scenarios where one is better than the other?

Yes, for simple components, functional components are usually preferred. For complex components with extensive state management, class components might be more suitable.

Can you give an example of a performance issue with class components?

Sure! A common issue is unnecessary re-renders due to state changes in parent components, which can be mitigated using React.memo with functional components.
