How can I manage global state in a React application using Context API?

You can manage global state in React using the Context API by creating a context, providing it at a higher level, and consuming it in your components.

Can you show me a simple example of how to set up a context?

Sure! First, create a context using const MyContext = React.createContext();. Then, wrap your components with MyContext.Provider and pass the value you want to share.

What about updating the context value from a child component?

You can use the useContext hook in the child component to access the context value and update it using a function passed down from the provider.

Are there any performance considerations I should be aware of?

Yes, be cautious about re-renders. Use memoization techniques like React.memo or useMemo to optimize performance.
