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

The Context API is a React feature that allows you to share state across components without prop drilling. You can create a context, provide it at a higher level in your component tree, and consume it in any child component.

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. Finally, use MyContext.Consumer or the useContext hook to access the value in child components.

What are the benefits of using the Context API?

The Context API helps avoid prop drilling, makes state management easier, and improves code readability by centralizing state.

Are there any drawbacks to using it?

Yes, overusing the Context API can lead to performance issues, as any change in context will re-render all consuming components. It's best used for global state.
