MERN Stack: Why is it the best choice for your next Web Application?

Combining JavaScript, CSS, and HTML in the usual way is no longer sufficient (although it gets the job done). For large enterprise web-based apps, taking advantage of a web stack has proven to be a viable solution to meet the demands of today’s digital audiences.

JavaScript (and its descendants, such as JSX, ES6, and others) is essentially the facilitator of stacks because it can easily connect numerous technologies (with the JSON data format).

Developers may now use JavaScript to construct application logic, front-end experiences, and database access, instead of merely adding pop-up windows and flashing headers.

Developers utilise a variety of stacks, but the two most popular are as follows:

  1. MEAN (MongoDB, ExpressJS, AngularJS, NodeJS)
  2. MERN (MongoDB, ExpressJS, ReactJS, NodeJS)

In this article, we will let you understand the key differences between these two full-stack frameworks, alongside giving you a brief analysis on which stack would be best suitable for your upcoming web application.

Before delving in, let’s have a glance at a basic difference between MERN and MEAN


1 It is an Open-Source JavaScript Library It is a JavaScript-based Development Stack
2 Uses JavaScript and JSX Uses TypeScript
3 Uses Virtual DOM Uses Regular DOM
4 Has Unidirectional Data Flow Has Bi-Directional Data Flow
5 Uses React.Js for Front-End Development Uses Angular.js for Front-End Development
6 Supports Mobile Applications Doesn’t support Mobile Applications


Both the frameworks have high-end features and extensive functionality. However, MERN has a slight upper hand in terms of the learning curve. Because the learning curves for Angular JS and React JS are different, MERN is easier to grasp and implement. 

Now, let’s take a closer look at the advantages of the MEAN and MERN stacks in order to properly comprehend the potential between the two.

MERN Vs MEAN: Benefits

  • A single coding script covers both the front end and the back end.
  • Only JAVA and JSON are required to finish the operation.
  • The MVC architecture allows for seamless development.
  • Built-in tools allow for real-time testing.
  • Runs on an open-source community with easily modifiable source code.
  • It is simple to create any form of application.
  • This stack is compatible with a variety of plug-ins and widgets. This is useful for development that must be completed within a specific time range.
  • Availability of the plug-ins enhances the functionality.
  • The open-source framework helps the developers to have access to community support.
  • The built-in tools allow for real-time testing.
  • The back end and the front end are written in the same language, improving synchronisation and enabling the applications to respond more quickly.

According to the HackerRank development skill report, 30% of developers choose AngularJS over React JS, while 26% sided with React JS. 

According to the research, 30% of programmers wished to learn React JS, and 35.9% of developers prefer to create using React JS, putting MERN slightly ahead of MEAN in terms of popularity.

MERN is now leading in terms of simplicity of understanding and popularity, as far as we know. Let’s look at a side-by-side comparison to see who will win the race in 2022.

MERN VS MEAN: A Comprehensive Analysis

Scalability: MEAN and MERN are both equally secure in terms of scalability and security. MERN, on the other hand, is at the forefront in terms of scalability.

Model View Controller: For enterprise-level projects, a comprehensive architecture is required. For this, MEAN is the preferable solution.

User Interface: MERN is the go-to stack for an advanced and simple UI. MERN makes it easier for users to interact.

User Experience: MEAN improves the experience by utilising third-party extensions, whereas MERN would necessitate additional setups.

Database: MERN is the ideal stack for CRUD (create, read, update, and delete). React JS is a fast-changing data framework with a pleasant user experience.

Support: MEAN’s AngularJS enables HTTP calls and brings the back-end together. Third-party app development will be required for enterprise-level apps.

Libraries:  React JS, on the other hand, enhances functionality with its extra libraries. In this area, MEAN has a slight advantage.


This detailed contrast has made us understand that the MERN stack outperforms the MEAN stack in terms of the learning curve, UI, scalability, and CRUD. Whereas MEAN, on the other hand, continues to lead in terms of community support. 

MEAN is more cost-effective and is the preferred platform for startups and small businesses. It’s simpler to switch between clients and servers. 

In MERN, the Virtual DOM improves the user experience while also speeding up the developer’s job. Because of the unidirectional data flow, React JS maintains a stable code. MERN is the way to go when it comes to writing for Android and iOS with JavaScript.

Though both are secure in the same way, the application of the stacks is fully dependent on the business requirements.

Your Take Away

MEAN is used by companies like Accenture, Raindrop, Vungle, Fiverr, and Sisense, among others. MERN stack is used by companies including UberEats, Instagram, and Walmart. Both stacks offer a fantastic user experience. Both stacks are capable of achieving stability and scalability.

As a result, we may infer that MEAN over MERN is required for enterprise-level projects. MERN simplifies the UI rendering process. Both are dependable when it comes to front-end development.

MEAN is an excellent choice for large-scale applications. MERN is useful for developing smaller apps more quickly.
