advanced patterns of Array.map with Async Function in React Component
I'm working with an scenario with using `Array.map` combined with an `async` function inside a React component. I want to fetch data for each item in an array asynchronously and then render the results. However, I noticed that the component renders before all the asynchronous operations complete, which causes some items to show stale or incomplete data. Here's a simplified version of my code: ```javascript import React, { useEffect, useState } from 'react'; const DataFetcher = ({ items }) => { const [data, setData] = useState([]); const fetchData = async (item) => { const response = await fetch(`https://api.example.com/data/${item}`); return response.json(); }; useEffect(() => { const fetchAllData = async () => { const results = await Promise.all(items.map(item => fetchData(item))); setData(results); }; fetchAllData(); }, [items]); return ( <div> {data.map((itemData, index) => ( <div key={index}>{itemData.name}</div> ))} </div> ); }; export default DataFetcher; ``` The key scenario is that while I'm using `Promise.all`, the rendering seems to kick off before the data fetching completes. For instance, if `items` is `[1, 2, 3]`, I sometimes see the output as: ``` Name: Name: Name: ``` which indicates that the `data` state is still empty when the component first renders. I've used `console.log(data)` to debug, and it shows that the data is populated after the initial render, which is not what I expected. I tried using `async` directly within `useEffect`, but that resulted in a warning about returning a promise. Is there a better way to handle this scenario in React to ensure all data is fetched before the component renders with the updated state? Any insights would be greatly appreciated!
