The document defines MERN as a stack comprising MongoDB, Express, React, and Node. MongoDB is a document database, Express is a Node.js web framework, React is a JavaScript frontend framework, and Node is a JavaScript web server. The MERN stack allows full-stack development with JavaScript, supports MVC architecture, and uses well-known open-source technologies. It describes the purpose of each component, with MongoDB storing data, Node.js providing runtime, Express building the backend, and React creating the frontend UI. The document also advertises an online course to learn the MERN stack.

2. What is MERN
 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

3. Benefits OF MERN
 Covers complete web development cycle from
frontend to backend with JS
 Supports MVC architecture for a smooth
development process
 As it is a JavaScript stack, developers can only be
pro in JSON and JavaScript
 Combination of the best technologies – MongoDB,
React, Node.js and Express.js
 as an extensive built-in suite to test tools
 It is an open-source framework backed by
community support

4. MERN COMPONENTS
 MongoDB: A document-oriented, No-SQL database used to
store the application data.
 NodeJS: The JavaScript runtime environment. It is used to
run JavaScript on a machine rather than in a browser.
 ExpressJS: A framework layered on top of NodeJS, used to
build the backend of a site using NodeJS functions and
structures. Since NodeJS was not developed to make
websites but rather run JavaScript on a machine, ExpressJS
was developed.
 ReactJS: A library created by Facebook. It is used to build UI
components that create the user interface of the single page
web application.
