What is Mern Stack? 

Mern Stack is a collection of frameworks, tools, and languages combined to develop a software product.

Some of the most popular technological stacks are LAMP(Linux, Apache, MySQL, PHP).

In this article, we will try to understand what is Mern Stack, what are their features? So, Without any further ado let’s get straight to it.

MERN is an acronym for MongoDB, Express Js, and Node Js etc. It is a combination of all above technologies based on JavaScript, and can be used together to build an advanced web application. It comprises both front-end and back-end development programs i.e. can we say full stack development.

Technology is used in Mern Stack

1. Mongo DB

It is an open source cross-platform DBMS. MongoDB stores the data collection in document home instead of tables and rows, like as a relational database. This enables faster accessing of documentation within the application.
