React 18: Unexpected behavior with useContext and dynamic rendering of components based on context state
I'm getting frustrated with I'm building a feature where I'm encountering an issue with React 18 where components that rely on context are not re-rendering as expected when the context state changes. I have set up a simple context provider that holds a user object and a function to update it. However, when I update the user object, some components that consume this context do not reflect the new state immediately. Here’s a simplified version of my context setup: ```javascript import React, { createContext, useContext, useState } from 'react'; const UserContext = createContext(); export const UserProvider = ({ children }) => { const [user, setUser] = useState({ name: 'John Doe', age: 30 }); const updateUser = (newData) => { setUser((prevUser) => ({ ...prevUser, ...newData })); }; return ( <UserContext.Provider value={{ user, updateUser }}> {children} </UserContext.Provider> ); }; export const useUser = () => useContext(UserContext); ``` My component that consumes this context looks like this: ```javascript import React from 'react'; import { useUser } from './UserContext'; const UserProfile = () => { const { user, updateUser } = useUser(); const handleAgeChange = () => { updateUser({ age: user.age + 1 }); }; return ( <div> <h1>{user.name}</h1> <p>Age: {user.age}</p> <button onClick={handleAgeChange}>Increase Age</button> </div> ); }; ``` When I click the button to increase the age, the `UserProfile` component sometimes does not update, and I see stale data. I've checked that `updateUser` is being called by adding a console log, which confirms that the function executes correctly. I've also verified that `UserProfile` is wrapped within `UserProvider`. However, sometimes it feels like the component does not re-render even though the state is updated. Am I missing something with the context or state management? Any insights or suggestions would be greatly appreciated. I am using React 18 and the latest version of React Router. For context: I'm using Javascript on macOS. Cheers for any assistance! Thanks in advance!
