What are the best practices for using useState in React?

When using useState, it's important to initialize state properly, avoid unnecessary re-renders, and use functional updates when the new state depends on the previous state.

Can you explain what functional updates are?

Functional updates allow you to pass a function to setState that receives the previous state as an argument, ensuring you always work with the latest state.

Are there any performance considerations I should be aware of?

Yes, avoid using useState for large objects or arrays directly. Instead, consider using useReducer for complex state logic.

How can I manage multiple state variables effectively?

You can group related state variables into a single state object or use multiple useState calls, depending on your component's needs.
