How the course is designed?

In MERN you will learn MongoDB which is classified as NOSQL document-oriented database. Data in MongoDB is stored in JSON based query language. It is flexible and easy to scale. Another component you will learn is Express popularly known as backend web application framework. The express framework is being used to develop robust web applications. Another component of MERN course is react which is JavaScript library popular to build user interface and interactivity on the client side. Some of the popular web applications like Facebook extensively uses react in the frontend for interactivity. React was first introduced by a developer in Facebook. React is an alternate to Angular JS (a frontend application development framework) which differentiates MERN from MEAN course. Node.js is a cross platform JavaScript runtime environment used to build scalable network applications.

Advantage of studying MERN

In this full stack developer course, MERN developer will use JavaScript on both the frontend and backend hence there is no need to learn a new programming language. Moreover, JavaScript is a loosely type language and easy to learn. A person having a knowledge of C programming can easily master JavaScript since the syntax of both the language is similar. Hence, a person having knowledge of C can easily excel JavaScript. There is a great scope of MERN stack developer in software companies these days. MERN stack developers are highly efficient for developing robust web applications across the web.


If you want to study MERN stack developer course then you need to have a basic understanding of web along with HTML and CSS.
