Routing in React is the process of managing navigation between different components or views within a single-page application (SPA). React uses React Router, a popular library, to handle routing and enable the dynamic rendering of components based on the URL.
Declarative: Declarative mode enables basic routing features like matching URLs to components, navigating around the app, and providing active states with APIs like <Link>, useNavigate, and useLocation.
Data : By moving route configuration outside of React rendering, Data Mode adds data loading, actions, pending states and more with APIs like loader, action, and useFetcher.
Framework: Framework Mode wraps Data Mode with a Vite plugin to add the full React Router experience.
