MERN stands for MongoDB, Express, React, Node, after the four key technologies that make up the stack.
MongoDB - document database
Express(.js) - Node.js web framework
React(.js) - a client-side JavaScript framework
Node(.js) - the premier JavaScript web server
MERN is one of several variations of the MEAN stack (MongoDB Express Angular Node), where the traditional Angular.js frontend framework is replaced with React.js. Other variants include MEVN (MongoDB, Express, Vue, Node), and really any frontend JavaScript framework can work.
How does the MERN stack work?
The MERN architecture allows us to construct a 3-tier architecture (frontend, backend, database) entirely using JavaScript and JSON.
BrowserRouter to keep our UI in sync with the URL. BrowserRouter helps with seamless transitions while switching between components. Basically, it will only reload/refresh the component that needs to be changed instead of refreshing/reloading the entire page.
