react async-await useEffect fetch JavaScript

I'm experimenting with Does anyone know how to I recently switched to I'm deploying to production and I've been struggling with this for a few days now and could really use some help... I'm stuck on something that should probably be simple... I'm working on a React application (version 17.0.2) where I'm using the `useEffect` hook to fetch data from an API whenever a specific state changes. I've noticed that even though I'm using `async/await`, the state update seems to happen before the fetch is completed, which leads to rendering stale data. My fetch function looks like this: ```javascript const fetchData = async () => { try { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } }; ``` And I'm calling this inside a `useEffect` like so: ```javascript useEffect(() => { fetchData(); }, [specificState]); ``` The question I'm working with is that `specificState` is changing rapidly based on user input, and by the time `fetchData` completes, the state might have changed again, causing the component to display outdated data. I'm also getting the following warning in the console: `Warning: A component is changing an uncontrolled input of type text to be controlled.`, which I suspect might be related to this scenario. I've tried adding a check to ensure that data is only set if the fetch matches the latest state, but it hasn't resolved the scenario. Any insights on how to handle this scenario effectively? Should I consider using a ref to store the latest state and prevent stale closures? Or is there a better pattern to follow here? This is part of a larger service I'm building. Thanks in advance! For context: I'm using Javascript on Windows 11. For context: I'm using Javascript on Linux. I recently upgraded to Javascript latest. I appreciate any insights! Any advice would be much appreciated. Any ideas how to fix this? This is my first time working with Javascript 3.11. Any feedback is welcome!
