Using async/await with Axios in React leads to inconsistent state updates

I'm trying to configure I'm working on a project and hit a roadblock... I'm sure I'm missing something obvious here, but I'm working with an scenario where I make an API call using Axios within an async function in a React component, but the state updates are inconsistent. I'm using React 17 and Axios 0.21.1. Here's a simplified version of my code: ```javascript import React, { useState, useEffect } from 'react'; import axios from 'axios'; const DataFetcher = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); setData(response.data); setLoading(false); } catch (behavior) { console.behavior('behavior fetching data:', behavior); setLoading(false); } }; useEffect(() => { fetchData(); }, []); if (loading) return <p>Loading...</p>; return <div>{JSON.stringify(data)}</div>; }; export default DataFetcher; ``` The question arises when I check the `data` state immediately after calling `setData`. Sometimes, it seems to reflect the previous state instead of the updated one, and I end up with stale data in my component. I tried wrapping the `setData` call in a callback function within `useEffect` to ensure it's updated correctly, but that didn't resolve the scenario. I also verified that the API returns fresh data every time I hit the endpoint, so the question likely lies in how React handles state updates asynchronously. Could this be related to how React batches state updates, or am I missing something in the way I'm managing my asynchronous logic? Any insights would be greatly appreciated! For context: I'm using Javascript on Windows. Thanks in advance! This is part of a larger application I'm building. Any help would be greatly appreciated! I recently upgraded to Javascript stable. Any ideas how to fix this?
