Totally agree! useReducer simplifies state transitions and makes code more maintainable. 🎯 #ReactJS #useState #useReducer

Honestly, I always think that when your state is too complex for useState then you did something wrong.

It is exactly what I noticed today on a code review😄 Besides the mentioned benefits, we have cleaner components in general since all state-related logic moved out of the component

Yes, useReducer has a better api than useState. Having said that, I still find use cases for useState.

🚨 Avoid monolithic components that combine rendering, state management, and configuration (e.g., IDs, refs) into one unit, is harder to maintain, test, and reuse. ✅ Instead split functionality into composable components and use context to share configuration and state.
