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

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

Class components are ES6 classes that manage state and lifecycle methods, while hooks are functions that allow you to use state and other React features in functional components.

Can you explain how state management differs between the two?

In class components, state is managed using this.state and updated with this.setState(). In hooks, you use the useState hook to manage state in a more concise way.

Are there any performance differences between them?

Generally, hooks can lead to better performance because they allow for more granular updates and can reduce the amount of code needed, but it depends on the specific use case.

Which one should I use for new projects?

For new projects, it's recommended to use hooks as they are the modern approach and provide a cleaner, more functional way to manage state and side effects.
