React 18 - State implementation guide correctly after async data fetch within useEffect
Does anyone know how to I'm confused about I'm experiencing an scenario in my React 18 application where the state doesn't update correctly after an asynchronous data fetch inside a `useEffect` hook. I have a component that fetches user data from an API and sets the state accordingly. However, after the data fetch completes, the state appears not to reflect the latest data when passed down to child components. The following is my current implementation: ```javascript import React, { useEffect, useState } from 'react'; const UserProfile = () => { const [user, setUser] = useState(null); useEffect(() => { const fetchUserData = async () => { const response = await fetch('https://api.example.com/user'); const data = await response.json(); setUser(data); }; fetchUserData(); }, []); return ( <div> {user ? <h1>{user.name}</h1> : <p>Loading...</p>} </div> ); }; ``` I noticed that even though the `user` state is updated after fetching, if I try to access `user` immediately after `setUser(data);`, sometimes it still shows the old value or `null`. To ensure the data has been fetched and state has updated correctly, I added a console log right after `setUser(data);`, but it logs the old state value instead. I also checked the network response and confirmed that the data from the API is correct. This scenario is causing problems for my conditional rendering logic as the child component relies on the updated `user` state to display user-specific data. Has anyone experienced similar issues with React 18? What could be causing this behavior? Is there a way to ensure the state reflects the latest data immediately after the fetch, or are there specific patterns to handle this in React? I'm developing on Ubuntu 20.04 with Javascript. Any examples would be super helpful. Any suggestions would be helpful. This is for a application running on Linux. Any advice would be much appreciated.
