What is the React Context API and how do I use it?

The React Context API is a way to manage state globally in a React application. It allows you to share values between components without having to pass props down manually at every level.

Can you give me an 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 a value to it. Any child component can access this value using MyContext.Consumer or the useContext hook.

What are the benefits of using the Context API?

The main benefits include avoiding prop drilling, easier state management, and improved code organization. It’s especially useful for global states like themes or user authentication.

Are there any drawbacks to using it?

Yes, one drawback is that it can lead to performance issues if not used carefully, as any change in context value will re-render all consuming components.
