advanced patterns of React's useEffect Hook with Dependencies in Nested State Updates
I'm working on a personal project and Can someone help me understand I'm collaborating on a project where I'm experiencing unexpected behavior with the `useEffect` hook in my React application when updating nested state... I'm using React 17.0.2 and I've set up a state object that contains an `items` array, which is further updated based on user interactions. The question arises when I'm trying to log the state inside the `useEffect` to see if it changes correctly. Here's a simplified version of the code I have: ```javascript import React, { useState, useEffect } from 'react'; const MyComponent = () => { const [state, setState] = useState({ items: [] }); const addItem = (newItem) => { setState(prevState => ({ ...prevState, items: [...prevState.items, newItem] })); }; useEffect(() => { console.log('Current items:', state.items); }, [state.items]); return ( <div> <button onClick={() => addItem('New Item')}>Add Item</button> </div> ); }; export default MyComponent; ``` When I click the 'Add Item' button, I expect to see the updated list of items in the console, but it logs the previous state instead. The `useEffect` seems to be firing before the state updates. I am aware that `setState` is asynchronous, but it feels like I'm missing something here. I've tried using a separate variable to store the new value and then set state, but that didn't resolve the scenario. Any insights on why this might be happening would be greatly appreciated! Is there a better way to handle this case? Any ideas what could be causing this? I'd be grateful for any help. I'm coming from a different tech stack and learning Javascript. Thanks in advance!
