Understanding the async behavior of useEffect with fetch and state updates in React 17
I'm collaborating on a project where I've looked through the documentation and I'm still confused about Quick question that's been bugging me - I am experiencing unexpected behavior with my React component when using `useEffect` to fetch data from an API. I am using React 17 and I have a simple fetch request that updates the component's state, but I notice that the state does not seem to update as expected after the fetch completes. My useEffect looks like this: ```javascript import React, { useEffect, useState } from 'react'; const MyComponent = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchData = async () => { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); setLoading(false); }; fetchData(); }, []); if (loading) return <div>Loading...</div>; return <div>{JSON.stringify(data)}</div>; }; export default MyComponent; ``` When I run the component, it shows 'Loading...' indefinitely, and upon inspecting the network tab, I can see that the fetch completes successfully. However, the component does not re-render with the fetched data. I have tried adding behavior handling within `fetchData`, but I still see the same loading state. I also checked if the API is returning the data in the expected format and it is. I suspect it might be an scenario with how state updates are batched in React or possibly related to stale closures, but I'm not sure how to debug it effectively. Any insights on why the state isn't updating or how to properly handle async data fetching in `useEffect` would be greatly appreciated. How would you solve this? My development environment is Windows. What am I doing wrong? I'm working in a Ubuntu 22.04 environment. I'd love to hear your thoughts on this.
