So, move ahead to know about the technology stack, because then you can understand MERN and MEAN effectively.

What Is Technology Stack?

As innovations and developments happing in the world, new technologies are coming. Or you can say, to deal with the problems effectively and timely, regular updates are needed in the world of app and website development. It leads to mergers and combinations of the best technologies.

So, the technology stack is a combination or collection of technologies. These can be the best programming languages, frameworks, and tools. This type of stack makes the work of the developers easy. When you read MERN vs MEAN, it should be clear in your mind what the technology stack is.

You can make a tech stack, but for this, you need to be clear about some questions below.

  • How to Analyze the business idea?
  • What are good examples of the tech stack?

What Is MEAN Stack?

When developers in a MEAN stack development company have knowledge about MongoDB, Expressjs, AngularJS, and NodeJS, they are called MEAN stack developers. Many people call these types of developers full-stack framework developers also.

So, the combination of these four technologies is called MEAN stack. Let’s know about all these technologies below.



  • MongoDB: It’s a NoSQL database system
  • Expressjs: It is a web framework to build web applications
  • AngularJS: A client-side Javascript framework developed by Google
  • NodeJS: Server-side Javascript execution framework

This is all about the MEAN stack. If you have knowledge about the same, you can hire mean stack developers effectively. Now, scroll down to know about another technology stack, the MERN stack.

What Is MERN Stack?

When you hire a MERN stack developer, make sure he has knowledge about MongoDB, Expressjs, React.js, and Node.js. This type of developer is also called full-stack developer by many people. Move ahead and know about this stack below.



  • MongoDB: It’s a NoSQL database system
  • Express.js: It is a web framework to build web applications
  • React.js: It is a Javascript library for designing UI
  • Node.js: It provides a cross-platform javascript runtime environment.

Several MERN stack development services providers discuss your business idea because they make sure this technology suits your idea or not.

The most used frameworks among developers worldwide have been several. But, there are top development frameworks that Statista highlights through its facts. The below-given statistics will help you understand which frameworks are widely used by the developers in 2021.



As you can notice in the statistics above that Reactjs was used more than any frameworks in 2021, so you can find a MERN stack developer easily.

But, you need to be clear about which technology stack would be better for your app or website. For this, it is important to know MEAN vs MERN in detail.

What is the Difference Between MERN and MEAN Stack?

In the previous details of both the technologies in this blog, you must have noticed there is one major difference. It is due to the use of Angular and React respectively. With the help of the below table, you can understand the negative and positive aspects of the MEAN and MERN technologies and their difference as well. Have a look.

Parameters MEAN Stack  MERN Stack
Language Javascript JavaScript, JSX
Type Javascript Framework Javascript Library
Features Moderate Level High Level
Performance Slower  Faster
Security High Medium
Data Binding One-way & two-way Only one way
DOM Regular DOM Virtual DOM
Data Flow Bidirectional Unidirectional
Scalability Medium High
Architecture  Component-Based Component-Based
Learning Curve Medium Low

By seeing the table, you can have an idea about the MERN stack vs the MEAN stack. For detailed information read about each parameter one by one.

  • Language: In the MERN stack, the Javascript JSX language is used. It is a statically typed object-oriented programming language. While in the MEAN stack, Javascript language is used.
  • Type: MEAN stack uses Javascript framework that is a collection of javascript code libraries. It helps the programmers to code fast and effectively. In the MERN stack, Javascript libraries are used; it helps in the easy and fast deployment of web applications.
  • Features: Knowing about the features helps understanding MEAN vs MERN better. You can develop efficient codes in a short time in the MERN stack. It has inbuilt testing tools like Jest and Mocha. MEAN is customizable with single language development, & stores data in JSON format.
  • Performance: With the advanced features MEAN makes the process of development fast and effective. Development in the MERN stack is even faster than the MEAN, likewise provides robust pages.
  • Security: MEAN stack offers high security and MERN provides medium-level security. But MERN ensures the durability of data storage. Generally, both are considered secure and robust.
  • Data Binding: In MEAN stack data binding can happen in both one and two ways. Whereas in the MERN stack, data binding takes place only in one way. This information will help you deal with mean stack development services providers.
  • DOM: MEAN stack updates the Document Object Model by using Angular. DOM is a programming interface for the languages XML and HTML. Whereas in the MERN stack DOM is virtual and uses React.
  • Data Flow: To understand the MERN vs MEAN stack, data flow is crucial. In MERN stack data flow is unidirectional, so it helps to deal with large projects. While, in the MEAN stack, if you alter the UI, it changes the model state at the same time. The reason is, MEAN stack is bidirectional.
  • Scalability: MEAN stack offers medium-level scalability while MERN offers high-level scalability. You can select any stack according to the need for scalability in your app or website.
  • Architecture: MEAN and MERN stack both are open-source, full-stack frameworks. They provide a complete development cycle from the front-end to the back-end development of the app or website.
  • Learning Curve: There is no major difference in the learning curve of both stacks. MEAN stack developers can also learn MERN stack. However, you will have to learn differently when it comes to Agular and React.

So, this is all about the difference and details of both stacks. When you hire developers from Technource, a MERN stack web development company, you can also discuss the MEAN stack. It is because we have developers for both technologies.
