MERN Stack

Introduction to MERN Stack?

MERN stack development is a free and open-source JavaScript software for building powerful front-end and back-end websites and applications. The term “MERN stack” is an assemblage of MongoDB, ExpressJS, React, and Node.js, all JavaScript-based technologies used to design web applications. As all MERN stack components are JavaScript based, this means MERN stack application is written in one language for both-ends server and client-side. It is easy to design web applications using Node.js as it provides a wide range of JavaScript modules. 

Advantages of developing web applications with MERN stack

• It is easier to make switching between client and server with mern stack
• Isomorphic Coding is possible with MERN stack
• Highly flexible
• MERN uses JSON
• Cost-effective
• High speed and reusability
• Open source and cloud company

Prerequisites of learning MERN stack   

1. HTML,
2. CSS and
3. Javascript
