Routing

A Single-Page Application (SPA) is a web application that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. This approach provides a faster, more fluid user experience, similar to a desktop application. Client-side routing is the mechanism that makes this possible. It allows you to define different 'routes' or URLs within your application (e.g., `/`, `/about`, `/products/:id`) and associate each route with a specific React component. When a user clicks a link, the router intercepts the navigation event. Instead of making a request to the server for a new HTML page, the router updates the URL in the browser's address bar and renders the corresponding component without a full page reload. The most popular library for implementing routing in React is React Router. It provides a set of components like `<BrowserRouter>`, `<Routes>`, `<Route>`, and `<Link>`. You wrap your application in `<BrowserRouter>` to enable routing. Then, you define your URL structure using `<Routes>` and `<Route>`, mapping a path to a specific component. To create navigation links, you use the `<Link>` component instead of a standard `<a>` tag. This ensures that navigation is handled by the client-side router instead of triggering a server request.
