What are the best practices for using useState and useReducer in React?

When using useState, keep state minimal and focused. For complex state logic, prefer useReducer.

Can you explain when to use useReducer instead of useState?

Use useReducer when managing state that involves multiple sub-values or when the next state depends on the previous one.

Are there any performance considerations I should be aware of?

Yes, useReducer can help avoid unnecessary re-renders by batching state updates, which can improve performance.

What about combining useState and useReducer?

You can combine them by using useState for local UI state and useReducer for more complex state management.
