React Form Controlled vs Uncontrolled: State Not Syncing on Input Changes

react form state-management JavaScript

I'm trying to debug I'm currently implementing a form in a React application using hooks, but I'm running into an scenario where my controlled inputs aren't syncing properly with the component state. I've set up my input fields to be controlled by state, but when I type into the input fields, the state does not update as expected. For instance, here's a simplified version of my code: ```javascript import React, { useState } from 'react'; const MyForm = () => { const [inputValue, setInputValue] = useState(''); const handleChange = (e) => { setInputValue(e.target.value); }; return ( <form onSubmit={(e) => e.preventDefault()}> <input type="text" value={inputValue} onChange={handleChange} /> <button type="submit">Submit</button> </form> ); }; export default MyForm; ``` Despite this setup, when I type in the input field, the `inputValue` state does not seem to reflect my input. I’ve verified that the `handleChange` function is being called (I even added a `console.log` inside it), and yet the input does not show the latest value. I also tried using an uncontrolled component approach by providing a `ref` to the input, and while that worked, I need to stick with controlled components for consistency in my application. I’ve gone through the official React documentation and tried different ways of managing state, but nothing seems to resolve this scenario. Is there something I'm missing here? Any help would be greatly appreciated! I'm developing on Ubuntu 20.04 with Javascript. I'm on Windows 10 using the latest version of Javascript. Thanks for your help in advance!
