Routing in ReactJS || MERN Stack

In ReactJS, routing is essential for building single-page applications (SPAs) that allow users to navigate between different components or pages without reloading the entire webpage. This is accomplished using the react-router-dom library, which provides a declarative way to manage routing. The library includes key components like Router, Route, Switch, and Link to handle navigation effectively.

The Router component (commonly BrowserRouter or HashRouter) acts as the primary wrapper for your application, enabling routing and ensuring that the UI stays in sync with the browser’s URL. The Route component is used to map specific URLs to corresponding React components. When a user visits a path that matches the Route, the respective component is rendered.
