Handling Multiple State Updates in Concurrent React Render Cycles

I'm following best practices but I'm following best practices but I'm not sure how to approach I'm working with an scenario with multiple state updates in a React component using hooks. When trying to update the state based on the previous state, I'm seeing unexpected results due to the concurrent rendering in React 18. Here's a simplified version of my component: ```javascript import React, { useState } from 'react'; const Counter = () => { const [count, setCount] = useState(0); const increment = () => { setCount(prevCount => prevCount + 1); }; const handleMultipleUpdates = () => { increment(); increment(); increment(); }; return ( <div> <p>Current Count: {count}</p> <button onClick={handleMultipleUpdates}>Increment by 3</button> </div> ); }; export default Counter; ``` When I click the button, I expect the count to increase by 3, but it only increments by 1 instead. I found that the updates are batched together, and since each update is based on the previous state, they are not accumulating as expected. I've also tried using a functional update pattern, but it seems like React is coalescing the state updates and only performing the last one. I'm not sure how to properly handle multiple state updates in scenarios like this without losing the expected results. Any suggestions on how to handle this correctly? What might be the best approach to ensure that my count updates as intended in concurrent mode? I recently upgraded to Javascript 3.9. I'd love to hear your thoughts on this. I'm working on a REST API that needs to handle this. Cheers for any assistance! This is for a CLI tool running on Ubuntu 22.04. Is there a better approach?
