Use React's Context API to manage global state and avoid 'prop drilling'.
In a typical React application, data is passed from parent to child components via props. While this works well for simple component trees, it can become cumbersome in larger applications. Imagine you have a deeply nested component that needs access to some piece of data from a top-level component, like the currently authenticated user or the application's theme. To get this data to the nested component, you would have to pass it down as a prop through every single intermediate component in the chain. This is known as 'prop drilling', and it can make your code verbose and difficult to maintain. The Context API is React's built-in solution to this problem. It provides a way to share state between components without having to explicitly pass props through every level of the tree. The API has three main parts. First, you create a context using `React.createContext()`. Second, you use the `Context.Provider` component to wrap a part of your component tree where you want the context to be available. The `Provider` accepts a `value` prop, which is the data you want to share. Third, any component within that Provider's tree can then subscribe to the context and consume its value using the `useContext` hook. This is perfect for managing 'global' state that many components need access to, such as theme information, user authentication status, or language preferences.
