How can I use the useReducer hook in complex applications?

The useReducer hook is great for managing state in complex applications. It allows you to handle state transitions more predictably than useState.

Can you give me an example of how to implement it?

Sure! You can start by defining your reducer function and initial state. Then, use useReducer in your component like this: const [state, dispatch] = useReducer(reducer, initialState).

What kind of scenarios is useReducer best suited for?

It's best suited for scenarios where you have complex state logic, like managing multiple related states or when the next state depends on the previous one.

Are there any performance considerations I should be aware of?

Yes, while useReducer can help with performance by reducing re-renders, it's important to ensure that your reducer function is optimized and doesn't cause unnecessary updates.
