How can I use the Context Hook in React for advanced state management?

The Context Hook allows you to share state across components without prop drilling. You can create a context, provide it at a higher level, and consume it in any child component.

Can you show me a code example of how to implement it?

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 if I want to update the context value from a child component?

You can use the useContext hook in the child component to access the context value and a function to update it. Just ensure the provider passes down the updater function.

Are there any performance considerations I should be aware of?

Yes, be cautious about re-renders. If the context value changes, all consuming components will re-render. You might want to memoize values or split contexts to minimize this.
