Conflicting state updates in a React component with both useState and useReducer hooks
I've been researching this but I'm building a feature where I keep running into I'm sure I'm missing something obvious here, but I'm encountering an issue where my component seems to behave unpredictably when using both the `useState` and `useReducer` hooks... I have a form where users can input data, and I'm using `useState` to manage some local inputs while `useReducer` handles more complex state logic for the overall form submission. However, when I update the local state, the changes don't seem to propagate correctly to the reducer, leading to stale values. Here’s a simplified example of my component: ```javascript import React, { useReducer, useState } from 'react'; const initialState = { data: null, loading: false }; const reducer = (state, action) => { switch (action.type) { case 'FETCH_START': return { ...state, loading: true }; case 'FETCH_SUCCESS': return { ...state, loading: false, data: action.payload }; default: return state; } }; const MyForm = () => { const [localInput, setLocalInput] = useState(''); const [state, dispatch] = useReducer(reducer, initialState); const handleChange = (e) => { setLocalInput(e.target.value); }; const handleSubmit = (e) => { e.preventDefault(); dispatch({ type: 'FETCH_START' }); // Simulating an API call setTimeout(() => { dispatch({ type: 'FETCH_SUCCESS', payload: localInput }); }, 1000); }; return ( <form onSubmit={handleSubmit}> <input type="text" value={localInput} onChange={handleChange} /> <button type="submit">Submit</button> {state.loading && <p>Loading...</p>} {state.data && <p>Data: {state.data}</p>} </form> ); }; export default MyForm; ``` The problem arises when I submit the form. Sometimes the `data` displayed is stale or empty, even though I'm entering valid input. I've checked the console, and the local state seems to update correctly, but the data prop in the state seems to reflect the previous input rather than the updated one. I've tried using `useEffect` to log changes to both `localInput` and `state.data`, but the logs show the correct values on change, yet the rendered output remains incorrect. I also verified that the reducer functions correctly in isolation. Any insights into why this might be happening or how I could resolve the state conflicts would be greatly appreciated! My development environment is Windows. I'd really appreciate any guidance on this. Any help would be greatly appreciated! Is this even possible? This is my first time working with Javascript 3.11.
