What Is The Mern Stack And The Future Scope Of Mern Stack Developer?

MERN Stack certification online

If you’re not completely new to the development game, you know that most modern applications are created with the help of a “stack” of various technological solutions. A “stack” refers to any combination of coding languages, tools, and frameworks developers use to create software products for their clients.
A stack contains different layers of components that play a vital role in the process of software product creation. All stacks are divided between the:

Client-side that is front-end (HTML, CSS, JavaScript)
Server-side that is back-end (OS, web server, programming language, web framework, databases)
In this blog we will discuss about one of the most trending stack, MERN Stack. Let’s first understand what MERN Stack is.


The MERN is similar MEAN stack but with a key distinction: the MEAN stack uses Angular to build front end web applications, while the MERN stack uses REACT to create them.
The MERN stack is comprised of four powerful web development technologies that, when used together, have far more efficient and effective results.

MERN is simply an acronym for these four technologies when used in tandem. They are:
MongoDB: An open-source, document-based database.
Express: A minimalist web framework for Node.js known for its speed.
React: A front end JavaScript library for creating user interfaces.
Node.js: A JavaScript runtime that operates on Chrome’s V8 JavaScript engine and brings JavaScript to the server.


The MERN stack’s main advantage in web development is that each line of code is written in JavaScript, which is a nearly universal programming language since it is vital for both server-side and client-side code. By using a single programming language, the MERN stack eliminates the need for context switching and greatly simplifies the entire development process, giving web developers the tools to create efficient web applications with far less effort. Technology stacks that use multiple programming languages leave developers to figure out for themselves how to properly interface them, but by using a JavaScript stack like MERN, developers only need to know JavaScript and JSON.

Working in the MERN stack delivers powerful results simply and efficiently. Knowing your way around the stack is an important skill set since building and deploying solid MERN apps is likely to gain importance in the future.

These days, MERN Stack is used extensively since everything is done in JavaScript. As you know, JavaScript is everywhere. It is used both on the front-end and back-end side. Because of this, there’s no need for context switching.

Tech stack that utilize multiple coding languages, force developers to figure out how to mix them together. Since MRN is JavaScript-based, developers only need to master a single coding language, which makes things a million times easier.

Node.js was built on Chrome’s JavaScript runtime to make it more conducive to building fast-operating network applications with easy scalability. The platform operates using a no blocking, event-driven I/O model that is incredibly efficient.

Node.js’s efficiency and simplicity make it an ideal platform for real-time applications running across distributed devices, especially those with intense data requirements. But Node.js has far more potential in conjunction with the MERN stack.

So, we can say that MERN Stack has bright future ahead. In order to get started with MERN Stack development, all you really need is a good understanding of JavaScript and ES6 Fundamentals, but also at least some familiarity with the basic concepts of React and Node.js.
There are many MERN Stack online training that will have you building your own dynamic web applications in no time. All you really have to do is pick the one that seems best to you and get started right away!
