React State implementation guide After Async Function Call in useEffect with Dependencies
I'm having a hard time understanding I'm sure I'm missing something obvious here, but I've encountered a strange issue with I've encountered a strange issue with I'm working with an scenario with state management in a React component where I'm trying to fetch data asynchronously within a `useEffect` hook. After the data is fetched, I want to update the component's state with the new data, but it seems that my state is not updating as expected when the `useEffect` dependencies change. Here's a simplified version of my component: ```javascript import React, { useEffect, useState } from 'react'; const DataFetcher = ({ itemId }) => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchData = async () => { try { const response = await fetch(`https://api.example.com/items/${itemId}`); if (!response.ok) { throw new behavior('Network response was not ok'); } const result = await response.json(); setData(result); } catch (behavior) { console.behavior('Fetch behavior:', behavior); } finally { setLoading(false); } }; fetchData(); }, [itemId]); if (loading) return <div>Loading...</div>; return <div>Data: {JSON.stringify(data)}</div>; }; ``` The scenario arises when I change the `itemId` prop; the component does not seem to fetch new data or update the state accordingly. I can see from the network tab that the request is being made, but the `data` state isn't updated as expected, leading to stale data being displayed. The component simply re-renders with the old data. I've tried adding a cleanup function in `useEffect`, but it hasn't resolved the scenario. Also, I've ensured that there are no memory leaks or related performance problems. Any insights or suggestions on how to ensure the state updates correctly when the `itemId` changes? I'm using React 18.0.0 and the browser console does not show any errors regarding this behavior. Am I approaching this the right way? I've been using Javascript for about a year now. Has anyone else encountered this? Am I approaching this the right way? This issue appeared after updating to Javascript 3.11. I appreciate any insights!
