<ul><li>Authentication is a critical part of many web applications, and securing routes in React requires an understanding of how tokens, such as JSON Web Tokens (JWT), work.</li><li>JSON Web Tokens (JWT) are compact, URL-safe tokens used to represent claims between two parties. JWT is a popular choice for authentication in single-page applications (SPAs) because it is lightweight, stateless, and easy to implement.</li><li>The implementation of JWT authentication in React involves setting up the backend with Node.js, Express, and JWT, and creating routes for login and protected data access. On the frontend side, React's useState and useEffect hooks are used to manage authentication state.</li><li>To protect routes, private routes are created using React Router, and access to protected routes is allowed only if the JWT token exists. This ensures that only authenticated users can access the protected routes.</li></ul>
