What are common mistakes when using useReducer in React?

What are some common mistakes developers make when using useReducer in React?

One common mistake is not initializing the state properly. It's important to provide an initial state that matches the expected structure.

Can you give me an example of a bad initialization?

Sure! If your state is supposed to be an object but you initialize it as an array, it can lead to errors when trying to access properties.

What about the reducer function itself?

Another mistake is mutating the state directly in the reducer instead of returning a new state object. Always return a new state to ensure React can detect changes.

How can I avoid these mistakes?

You can avoid these mistakes by thoroughly testing your reducer and ensuring you understand the structure of your state before implementing it.
