What are the use cases of useContext hook?

The useContext hook in React is used to share data across components without having to pass props manually through each level. Here are some common and effective use cases:

1. Theme Customization useContext can be used to manage application-wide themes, such as light and dark modes, ensuring consistent styling and enabling user-driven customization.
2. Localization and Internationalization It supports localization by providing translated strings or locale-specific content to components, adapting the application for users in different regions.
3. User Authentication and Session Management useContext allows global access to authentication status and user data. This enables conditional rendering of components and helps manage protected routes or user-specific UI elements.
4. Shared Modal or Sidebar Visibility It's ideal for managing the visibility of shared UI components like modals, drawers, or sidebars, especially when their state needs to be controlled from various parts of the app.
5. Combining with **useReducer** for Global State Management When combined with useReducer, useContext becomes a powerful tool for managing more complex global state logic. This pattern helps maintain cleaner, scalable state logic without introducing external libraries like Redux. Some of the common use cases of useContext are listed below,
