Course Description:

MERN Stack is one of the most popular Technology Stack. It is used to develop a Full Stack Web Application. Although it is a Stack of different technologies, all of these are based on JavaScript language.
MERN Stands for:

  1. M – MongoDB
  2. E – Express
  3. R – React
  4. N – Node.js

This stack leads to faster development as well as the deployment of the Web Application. React is Frontend Development Framework whereas Node.js, Express, and MongoDB are used for Backend development
