Technology is evolving at a rapid rate. But how rapid? The pace of technological innovation grows two times every 18 months when computing is measured. Not only this, but over 89 percent of big data has also been produced in the last two years. These stats and figures show how technology is advancing.

technological innovation grows two times every 18 months when computing
is measured. Not only this, but over 89 percent of big data has also been
produced in the last two years. These stats and figures show how technology
is advancing.
It’s a clear sign that the future of technology doesn’t seem to be slowing
down. Right? But at the same time, small or enterprise-level businesses are
also stressed to walk with technology trends. This urge leads them to launch
a web and mobile app that further end them with a question - 'Which
technology stack should I choose for digital product development, especially
when I have the fastest growing MERN and MEAN stack on my list?
Choosing the right technology between MERN and MEAN is not easy. After
all, both technology stacks are used to develop advanced web and mobile app
solutions for small and large-scale businesses. Well, in order to clear up your
confusion, we bring you this blog. Here we have highlighted the comparison
between MEAN stack and MERN stack development that will shed a light on
each aspect of these technologies.
So, what are you waiting for?
Let’s delve more into this topic to get answers to all your questions.

3. What is MEAN Stack?
An open-source, JavaScript-based technology
stack, MEAN is popular for mobile and web app
development. MEAN stands for MongoDB,
ExpressJS, Angular, and NodeJS respectively.
This stack comes with essential plugins and tools
required to build robust web and mobile app
solutions embracing a top-grade user experience.

4. Key Features
Know the power of the MEAN stack development by checking out the
below-listed features.
● MongoDB
It’s a database program and one of the components of the MEAN stack that
makes the insert, update, and delete process easier.
● JavaScript
JavaScript is a popular web programming language used to build high-
performance websites and games.
● NodeJS Driven
MEAN stack is a NodeJS-driven technology stack that helps render
databases faster than the Apache server.
● Isomorphic Code
Isomorphic code works best with the JavaScript programming language as it
can run on both client and server end.

5. Benefits
● Developers can expect reusability, maintenance,
testability, and high speed from the MEAN stack.
● Every component of the MEAN stack is free and
open-source, which cuts down the development
cost to a high extent.
● Isomorphic coding is possible with the MEAN
stack. It makes it easy for developers to transfer
the code to another framework.
● MEAN stack allows effortless switching between
server-side and client-side. Developers having
expertise in JavaScript can handle such projects.

6. What is MERN Stack?
MERN stack is another name categorized as
full-stack that also helps develop hybrid web
and mobile apps. MERN stands for
MongoDB, ExpressJS, ReactJS, and NodeJS,
used by developers worldwide.

7. Key Features
Here are a few points showing why developers worldwide are attracted to this
MERN technology stack.
● Runs on Multiple Servers
MongoDB in the MERN stack development can run on multiple services.
● Testing
The testing tools, including Jeta, and Mocha, allow you to perform testing on
web and mobile applications based on ReactJS.
● Hybrid Mobile Apps
Developing a hybrid app is possible with the MERN stack. Thanks to React
Native! It is a hybrid platform that encourages a smoother development
process.
● Purely Javascript-based
MERN stack is purely a JavaScript-based technology stack. Hence, it requires
no context switching, as every line of code is written in JavaScript.

8. Benefits
● Building a top-notch web and mobile application is
easy using the development tools React library offers.
● MERN stack offers incredible community support.
● It provides access to in-built testing tools.
● MERN stack offers the flexibility of creating pages on
the server.
● Support Model View Controller (MVC) architecture for
a smooth development process.
● In order to use this JavaScript-based stack, you must
have a good knowledge of JavaScript and JSON.

9. MEAN or MERN: A Detailed
Comparison
Now you're very well aware of what MEAN and
MERN stack development is. Both technologies
serve the same goals (developing web and mobile
app solutions). So, how would you choose the most
notable technology that suits your business
requirements?

10. MVC Support
Prioritizing the entire architecture is necessary when
developing an enterprise-level application. In such a
case, choosing the MEAN stack is a wise move instead
of the MERN stack as the MEAN stack supports Model-
View-Controller architecture. But if you can manage the
code, choosing the MERN stack would be the best idea.
Performance
DOM (Document Object Model) is the programming
interface for HTML and XML documents. MERN uses
React for a virtual DOM update that enables faster
application coding. On the other hand, the MEAN stack
utilizes Angular for real DOM updates.

11. Learning Curve
NodeJS, MongoDB, and ExpressJS contain extensive documentation,
and there is not much difference in the learning curve of both MEAN
and MERN. The whole learning curve changes between React and
Angular.
The Angular framework uses templates and Typescript. So, there is a
much learning curve with Angular. On the other hand, React doesn’t
contain a learning curve.
Security
Scalable frameworks like NodeJS and Angular, supported by JSON
Web Token (JWT), build together a MEAN stack. Such components
ensure no unauthorized access can harm your sensitive data, making the
MEAN stack more secure than the MERN stack.
When discussing the MERN stack, it enables faster execution of
operations, building an API backend along with Hapi, Express. MERN
stack also offers authentication methods, but at the same time, it is
important to note these methods are ineffective against CSRF attacks.

12. Data Flow
MEAN stack allows you to alter UI and model as per your choice,
and this is possible because the data flow of the MEAN stack is bi-
directional. On the other hand, React's unidirectional data binding is
considered ideal when handling and managing large-scale projects.
Third-party Libraries
MEAN stack has HTTP requests and is equipped with backend
functionalities by default. It directly points to the fact you can use
the libraries without any knowledge of programming language.
Well, the MERN stack is still advancing and has no libraries to meet
the requirement of project development. Additional settings are
required to integrate third-party libraries in React.

13. Final Words
There is no second thought that there is a close
competition between the MEAN stack and MERN
stack. Choosing the right one is not easy. Both
technology stacks are best in their own ways. So, you
can select any as per your business requirement in
order to develop a high-end dynamic app.
