The MERN Stack is a popular full-stack web development framework that combines four key technologies: MongoDB, Express.js, React, and Node.js. Each component of the stack serves a specific purpose in building modern web applications. Developers commonly use code editors or integrated development environments (IDEs) like Visual Studio Code for MERN Stack development.

What is Mernstack ?
MERN stack refers to a collection of JavaScript based technologies which are used in the development of websites. MERN is the acronym for Mongo DB, Express JS, React JS, and Node JS. All of these play an integral part in transferring database from client to server.
Mongo DB is a NoSQL database system. Mongo DB is used to save data in the format of binary JSON, making the transfer of information between server and client easier.
Express, being a lightweight framework is used in the building of web application in Node. Inspired from Ruby framework, Express is equipped to multiple robust features.
Robust is a library of JS which can be used instead of Angular for front end development. It is supported by Facebook.
Node.js is a serverside platform which is built on Google Chrome’s V8 JavaScript runtime.
