If you're working on a full-stack web application, GitHub Copilot can help you generate code snippets for common tasks such as user authentication, routing, and API integrations. Its ability to provide context-aware code suggestions will speed up your workflow and improve code quality.

Let's examine this example more concretely:

You're building a React application with a Node.js backend and need to implement user authentication. You create a new file called `AuthContext.js` and write a comment:

// Create a React context for user authentication with login, logout, and registration functions
// Should handle JWT tokens, store user info in local storage, and provide loading states

Based on this comment, GitHub Copilot might generate a complete implementation including:

1. Context Creation: A React context structure with appropriate state management for user information, authentication status, and loading states.
2. Authentication Functions: Implementation of login, logout, and registration functions that interact with your backend API and handle JWT tokens correctly.
3. Local Storage Integration: Code for persisting authentication state across page refreshes using local storage, with appropriate security considerations.
4. Custom Hooks: Utility hooks like `useAuth()` that make it easy to access authentication state and functions throughout your application.
5. Error Handling: Robust error management for various authentication scenarios, including invalid credentials, network failures, and expired tokens.

As you continue development, GitHub Copilot will suggest complementary components like protected routes, login forms, and profile management interfaces that maintain consistency with your authentication implementation. The tool adapts to your coding style and naming conventions, ensuring that generated code feels like a natural extension of your existing work.
