CSS, HTML and Javascript are the foundations of Web development, however they are no longer sufficient to meet all development requirements. So we now have two technological stacks, MERN and MEAN, that are popular among developers. Let’s have an overview of the MERN Stack.

MERN Stack is based on JavaScript. It is used to make full-stack web application deployment easier and faster. MERN Stack is made up of four technologies:

1. MongoDB: Cross-platform, document-oriented, No-SQL database.
2. Express: Back-End Framework using NodeJS functions and structures.
3. React: Front-End Library
4. Node.js: JavaScript Runtime Environment

Why use MERN stack?
This is indeed a typical inquiry that every developer receives from newbies to the profession. There are a few arguments for this:

1. It allows you to build both web and mobile-based applications.
2. Because the whole stack is based on one language, devs do not need to learn and switch gears to work with different technology.
3. All of the technologies used in MERN stack are open-source.
4. The developer community surrounding the MERN stack is massive and rapidly increasing.
