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

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

The main differences include state management, lifecycle methods, and syntax. Hooks allow functional components to manage state and side effects without needing classes.

Can you explain how state is managed differently in both?

In class components, state is managed using this.state and this.setState(). In hooks, you use the useState hook to manage state in functional components.

What about lifecycle methods? How do they differ?

Class components use lifecycle methods like componentDidMount and componentWillUnmount. Hooks use the useEffect hook to handle side effects, which can replicate these lifecycle methods.

Are there any performance differences between the two?

Generally, hooks can lead to better performance due to less overhead, but it depends on how they're implemented. Class components can be more verbose and may introduce unnecessary complexity.
