Problem Statement
How does RTK improve TypeScript support compared to vanilla Redux?
Explanation
RTK provides excellent TypeScript support with better type inference for state, actions, and dispatch, eliminating much of the manual typing required in vanilla Redux. createSlice automatically infers action types from reducer names, configureStore infers the RootState and AppDispatch types, and the builder callback pattern in extraReducers provides type-safe handling of actions. RTK also includes pre-typed hooks like useAppDispatch and useAppSelector that know your exact state shape, and createAsyncThunk properly types the payload creator arguments and return values, making TypeScript development much smoother.
