How can I use React Context for global state management?

You can use React Context to create a global state by defining a context and a provider component. This allows you to share state across your application without prop drilling.

Can you show me a simple example?

Sure! First, create a context using const MyContext = React.createContext();. Then, wrap your app in a provider: <MyContext.Provider value={/* your state */}>...</MyContext.Provider>. You can access the context in any component using const value = useContext(MyContext);.

What are the benefits of using Context over Redux?

Using Context is simpler for small to medium applications, as it avoids the boilerplate of Redux. However, Redux is more powerful for complex state management.

Are there any performance concerns with using Context?

Yes, if the context value changes frequently, it can cause unnecessary re-renders. To mitigate this, you can split your context or use memoization.
