React: State implementation guide as Expected with useEffect and Async Function

react useeffect async-await JavaScript

I've been researching this but I'm reviewing some code and I recently switched to This might be a silly question, but I'm working with an scenario with state updates in my React component... I'm using the `useEffect` hook to fetch data asynchronously and then update the component's state. However, after the state is updated, the component does not seem to re-render with the new state. Here’s a simplified version of my code: ```javascript import React, { useState, useEffect } from 'react'; const MyComponent = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchData = async () => { setLoading(true); try { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } finally { setLoading(false); } }; fetchData(); }, []); if (loading) return <div>Loading...</div>; return <div>Data: {JSON.stringify(data)}</div>; }; export default MyComponent; ``` I’ve also added a console log to check the value of `data` after the `setData(result)` call, and it logs the correct value, but the component only shows `Loading...` indefinitely. I've ensured that my API endpoint returns valid JSON and that there are no CORS issues. I also checked the network requests, and everything looks fine. Could this be a question with how `useEffect` is managing the asynchronous calls, or is there something about the state update that I’m missing? Any insights would be greatly appreciated! Any ideas what could be causing this? The stack includes Javascript and several other technologies. Cheers for any assistance! I'm working with Javascript in a Docker container on Windows 10. What are your experiences with this? This issue appeared after updating to Javascript 3.10. Thanks for your help in advance!
