React 18: Handling Race Conditions in Concurrent Features with Suspense and useTransition

Quick question that's been bugging me - I'm a bit lost with I've looked through the documentation and I'm still confused about I'm not sure how to approach I'm using React 18 and trying to implement a feature where multiple data-fetching requests can occur concurrently using `Suspense` and `useTransition`... However, I'm running into a race condition scenario where the UI flickers and doesn't display the latest data correctly. I set up `useTransition` like this: ```javascript const [isPending, startTransition] = useTransition(); const fetchData = async () => { startTransition(async () => { const response = await fetch('/api/data'); const jsonData = await response.json(); setData(jsonData); }); }; ``` But what seems to be happening is that if I trigger `fetchData` multiple times quickly, the state updates are getting mixed up, and I see stale data reflected in the UI. I tried using `setData` conditionally based on a versioning system of the response, but it still doesn't seem to resolve the flickering scenario. The console doesn't show any warnings or errors, but the user experience is definitely affected. Is there a better way to manage concurrent updates in React 18 using `Suspense` and `useTransition`, or do I need to implement a more robust mechanism to handle these state updates? Any best practices or patterns would be greatly appreciated! Any advice would be much appreciated. I'm working in a Debian environment. What am I doing wrong? My team is using Javascript for this web app. Thanks in advance! I'm using Javascript LTS in this project. Thanks for taking the time to read this!
