react hooks usestate usereducer JavaScript

I tried several approaches but none seem to work. This might be a silly question, but I'm encountering an issue with updating a deeply nested state object using React's `useReducer` hook. I have a state structure that looks like this: ```javascript const initialState = { user: { name: '', details: { age: 0, address: '' } } }; function reducer(state, action) { switch (action.type) { case 'UPDATE_ADDRESS': return { ...state, user: { ...state.user, details: { ...state.user.details, address: action.payload } } }; default: return state; } } ``` I dispatch the action like this: ```javascript const [state, dispatch] = useReducer(reducer, initialState); dispatch({ type: 'UPDATE_ADDRESS', payload: '123 Main St' }); ``` However, when I log the state after dispatching, I see that the address is updated correctly, but when I try to log `state.user.details.address` immediately after the dispatch, it still shows the old address value. This seems to happen because of the asynchronous nature of the state updates in React, but I expected that the state would reflect the most recent change. I’ve also tried using a `useEffect` to watch for changes, but that doesn’t seem to resolve the immediate logging issue. Here’s what I tried: ```javascript useEffect(() => { console.log('Address updated:', state.user.details.address); }, [state.user.details.address]); ``` With this setup, I can see the change in the console, but I still can’t access the updated value right after dispatching. Is there a way to handle this to ensure that I can immediately access the updated state right after a dispatch? Any help would be greatly appreciated! Any help would be greatly appreciated! I'd really appreciate any guidance on this. Hoping someone can shed some light on this.
