What are some common mistakes when using useReducer in React?

Some common mistakes include not initializing the state properly, forgetting to return the new state, and using complex logic in the reducer.

Can you explain why initializing the state is important?

Initializing the state is crucial because it sets the starting point for your reducer. If not done correctly, it can lead to undefined states.

What happens if I forget to return the new state?

If you forget to return the new state, the component won't re-render with the updated state, leading to stale or incorrect UI.

Are there best practices for structuring my reducer?

Yes, it's best to keep your reducer pure, avoid side effects, and structure it to handle different action types clearly.
