What are some advanced patterns for using useReducer in React?

Advanced patterns for useReducer include combining it with useContext for global state management, using middleware for side effects, and implementing lazy initialization.

Can you explain how to combine useReducer with useContext?

Sure! You can create a context and a provider component that uses useReducer to manage state. This allows you to access the state and dispatch function from any component within the provider.

What about using middleware with useReducer?

You can create a custom middleware function that intercepts actions before they reach the reducer. This is useful for logging, handling asynchronous actions, or triggering side effects.

Are there any performance considerations I should be aware of?

Yes, be mindful of how often your state updates and how components re-render. Using memoization techniques like React.memo can help optimize performance.
