React useState with complex objects implementation guide correctly on nested properties
I'm trying to debug I'm trying to configure I'm wondering if anyone has experience with I've encountered a strange issue with After trying multiple solutions online, I still can't figure this out..... I'm working on a React application using version 17.0.2, and I'm having an scenario where my state updates are not reflecting correctly when dealing with nested properties in a complex object. Here's a simplified version of my component: ```javascript import React, { useState } from 'react'; const App = () => { const [user, setUser] = useState({ name: 'Alice', details: { age: 25, city: 'New York' } }); const updateCity = () => { setUser(prevUser => { return { ...prevUser, details: { ...prevUser.details, city: 'San Francisco' } }; }); }; return ( <div> <h1>{user.name}</h1> <p>City: {user.details.city}</p> <button onClick={updateCity}>Change City</button> </div> ); }; export default App; ``` When I click the "Change City" button, I expect the city to update to "San Francisco", but it remains "New York". I've checked that the `updateCity` function is being invoked, but the state doesn't seem to update as I expect. I've tried using a functional update for `setUser` to ensure I get the latest state, and I'm spreading the previous state correctly, but for some reason, the UI does not re-render with the new state. I also confirmed that my component is not getting unmounted or anything weird like that. Is there something I'm missing regarding React's state management with nested objects? Any help would be appreciated! I'm working on a CLI tool that needs to handle this. Is there a better approach? The project is a microservice built with Javascript. This is part of a larger service I'm building. How would you solve this? My team is using Javascript for this application. Am I approaching this the right way? For context: I'm using Javascript on macOS. Is there a better approach?
