react axios ajax JavaScript

I need help solving I recently switched to I'm working on a project and hit a roadblock... I'm having trouble with an AJAX call in a React component where I'm using Axios to fetch data from an API. The response seems to be correct, but when I set the state with the fetched data, the component doesn't re-render as expected. I've ensured that I'm correctly using the `setState` method in the promise resolution, but it seems like the state remains unchanged. Here’s a simplified version of my code: ```javascript import React, { useEffect, useState } from 'react'; import axios from 'axios'; const MyComponent = () => { const [data, setData] = useState(null); useEffect(() => { const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); console.log('Response received:', response.data); setData(response.data); } catch (error) { console.error('Error fetching data:', error); } }; fetchData(); }, []); console.log('Current state:', data); return ( <div> <h1>Data:</h1> {data ? <pre>{JSON.stringify(data, null, 2)}</pre> : <p>Loading...</p>} </div> ); }; export default MyComponent; ``` After running this code, the console.log for `Current state:` shows `null` even after the Axios call should have completed successfully. I’ve checked the network tab and verified that the response is valid JSON. I also tried adding a dependency array to the `useEffect`, but that didn't change the behavior. Is there something I'm missing regarding state updates or how the component handles them? Any insights would be appreciated! For context: I'm using Javascript on Windows. What am I doing wrong? This is part of a larger CLI tool I'm building. Thanks in advance! This is happening in both development and production on Ubuntu 20.04. Could this be a known issue? I'm using Javascript latest in this project.
