React useEffect dependency array not updating state correctly on prop change
I'm stuck trying to I'm a bit lost with I'm building a feature where I'm sure I'm missing something obvious here, but I'm working with a React component that uses `useEffect` to update its internal state based on a prop change... The issue I'm facing is that the state isn't updating as expected when the prop changes. I've tried logging both the prop and the state inside the `useEffect`, but it seems like the state value isn't reflecting the latest prop value. Here's a simplified version of my code: ```javascript import React, { useEffect, useState } from 'react'; const MyComponent = ({ externalData }) => { const [internalData, setInternalData] = useState(null); useEffect(() => { console.log('External Data:', externalData); setInternalData(externalData); }, [externalData]); useEffect(() => { console.log('Internal Data:', internalData); }, [internalData]); return <div>{internalData}</div>; }; export default MyComponent; ``` In this setup, I'm expecting `internalData` to update whenever `externalData` changes. However, when I log `Internal Data`, it still shows the previous value of state instead of the updated one which corresponds to `externalData`. I've also verified that `externalData` is indeed changing by logging it right before I set `internalData`. Am I missing something in how state updates in React work, particularly regarding closures in `useEffect`? I've also tried using a function updater like `setInternalData(prev => externalData)` but that did not solve the issue either. Any insights would be greatly appreciated! I'm using React 17.0.2. For context: I'm using Javascript on macOS. Is this even possible? The stack includes Javascript and several other technologies. Could this be a known issue? I'm on Linux using the latest version of Javascript. What's the best practice here?
