MERN stack is a combination of technologies used for building full-stack web applications. It consists of four main components: MongoDB - a NoSQL document database used for storing and retrieving data. Express.js - a web application framework used for building RESTful APIs and web applications. React.js - a JavaScript library used for building user interfaces and handling view rendering on the client-side. Node.js - a server-side JavaScript runtime used for building scalable and efficient server-side applications.
