useState vs useReducer: Which to Use?

What's the difference between useState and useReducer in React?

useState is a hook for managing state in functional components, while useReducer is better for complex state logic.

When should I use useReducer instead of useState?

Use useReducer when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one.

Can you give me an example of when to use each?

Sure! Use useState for simple state like a toggle, and use useReducer for managing form state with multiple inputs.

Are there performance differences between the two?

Generally, useReducer can be more performant for complex state updates, as it batches updates more effectively.
