The world of technology is changing rapidly and there are many reasons for this. These are the times when a more sophisticated and advanced technology that replaces everything else comes on the market.

Sometimes the global changes in the world situation influence the shaping of technological trends. For example, a global pandemic that has long and irrevocably changed the world of business and technology. 

In this article we will talk about two technology complexes : MEAN Stack and MERN Stack.

If you’re not a technician but a business owner, don’t worry, after this article you will learn how to distinguish technology stacks and will choose the developers you need for your projects.

We often like to recall a well-known Sir F. Bacon’s “Knowledge is Power” phrase. Information that can affect the outcome of your business can’t be superfluous, can it?


What is Stack Technology?




But what is Stack technology? It is nothing more than a mix of various programming languages, frameworks, libraries, tools and UI / UX solutions. With the creation of mobile and web applications, these development stacks come in two types – applications and technologies.

What is MEAN Stack?



The MEAN stack is JavaScript-based framework for developing web applications. 

While MEAN is mainly suited for real-time applications, particularly those running natively in the cloud and single-page (dynamic) web applications built in Angular.js, it can be used for other use cases as well, such as:

  • Workflow management tools
  • News aggregation sites
  • Todo and calendar applications
  • Interactive forums.

And much more.

Since all the components are based on JavaScript and JSON, the integration between the components of the stack is intuitive and straightforward.

Additionally, the E and A of MEAN (Express and Angular) are two of the most popular and well-supported JavaScript frameworks for back-end and front-end development, respectively. Express makes routing and managing HTTP requests and responses super easy, and includes great support for middleware to handle JSON endpoints and form posts. Angular is a powerful tool for building dynamic HTML pages that communicate with a back-end server.

Whether you’re building a high-throughput API, a simple web application, or a microservice, MEAN is the ideal stack for building Node.js applications.

All of the MEAN stack components are open source in nature and therefore allow a generous, free-of-charge opportunity for the developers.





The MERN is similar to the MEAN Stack but with a key difference: the MEAN stack uses Angular to build front end web applications, while the MERN stack uses REACT to create them.

The MERN stack consists 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.

Facebook, Instagram, WhatsApp, DropBox, and NetFlix are the five most famous mobile apps built with MERN Stack.

The main advantage for developers using the MERN stack is that each line of code is written in JavaScript. It is a programming language that is used everywhere for both client-side and server-side code. With one language between levels, there is no need to change the context.

For a technical stack with multiple programming languages, developers must figure out how to merge them. With the JavaScript stack, developers must only own JavaScript and JSON.

In general, the use of the MERN stack allows developers to create high-performance web applications.


In Conclusion



The main difference between MEAN and MERN is that the MEAN stack uses AngularJS (supported by Google), while the MERN stack uses the ReactJS library (from Facebook). Both use JavaScript as a programming language, which makes encoding much faster.

If you want to create an Enterprise-level application or a large-scale operation like Ecommerce, then MEAN stack will be the preferred option. This is due to its ability to update the code as needed. If you prefer smooth user interaction, the MERN stack would be better.

Anyway, you have to understand that trends are not always the right choice. First of all, you have to consider the purpose and the mission of your project in order to find the right technology and get the desired result.
