React useEffect not firing on state change when using functional updates with async API calls
I'm experimenting with I've been banging my head against this for hours... Hey everyone, I'm running into an issue that's driving me crazy... I'm working with an scenario where my `useEffect` hook in a React component doesn't seem to fire when the state is updated using functional updates after making an async API call. 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 () => { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); setLoading(false); }; fetchData(); }, []); useEffect(() => { if (data) { console.log('Data updated:', data); // Do something with data } }, [data]); return <div>{loading ? 'Loading...' : JSON.stringify(data)}</div>; }; export default MyComponent; ``` The first `useEffect` successfully fetches the data and sets it in the state, while the second `useEffect`, which is supposed to log the updated data, does not seem to trigger when `data` is updated. I've confirmed that the data is indeed being fetched correctly and `setData` is called with the new value. I'm using React 17.0.2 and the latest version of React Hooks. I've tried using different configurations for the dependency array, including leaving it empty and using `loading` as a dependency, but neither seems to resolve the scenario. I also checked the console for any errors or warnings, but nothing shows up. Could this be due to the way I'm updating the state with async calls? Is there something I'm missing in the dependency management of `useEffect`? Any guidance would be greatly appreciated! My development environment is macOS. What are your experiences with this? This is part of a larger REST API I'm building.
