Mean stack uses Angular, whereas Mern stack uses React.
React o ers you the freedom to pick tools, libraries, and architecture for
developing web applications, whereas Angular gives you less freedom and

If you are techno-friendly, you know that a stack is nothing but an
amalgamation of frameworks, coding languages, tools, and libraries that
developers use to create robust web applications.
Mern-Stack uses four components to create
e ective web applications. These are:

to build up back-end web applications. It runs on top of the NodeJS,
maintaining the server and its routes.
Key features
ExpressJS simpli es server code writing, and developers don't need to
write the same code repeatedly.
It is well known for its fast speed and minimal architecture.
Express is used to create single-page, multi-page, and hybrid web
applications.
3. ReactJS
ReactJS is an open-source Javascript library that is used to create front-
end web applications. It facilitates the way for developers to use a single
code base on multiple platforms. Moreover, ReactJS o ers tools to build
scintillating user interfaces that enhance the quality of front-end web
pages.

rendering.
React has vast community support as well that enables connectivity
amongst developers.
4. NodeJS
NodeJS is an open-source platform that is considered to be a Javascript
runtime environment. It deploys the code outside the browser, on the

4. back-end side.
Key features
NodeJS library executes quick coding and enhances scalability.
It is easy to use and paves the way for ExpressJS to work e ciently.

language is the most awesome one. Javascript is the language that is
used for both web page development, i.e., front-end and back-end.
Thus, it eliminates the need for content switching, enabling the
developers to build applications in less time and e ort. On the other hand,
the technology stack that deals with multiple languages create problems
for developers to build e cient applications.
Developers need only to be acquainted with the use of the Javascript
language and JSON.
The four components mentioned above of the Mern stack are well
enough to create e cient web applications.
Mern stack o ers the MVC(Model view controller) architecture to
ensure the smooth ow of the web applications.
It allows developers to complete the development cycle from the
front-end to back-end pages of the web apps.
The most bene cial feature of the Mern stack is cost-e ective as it
provides all development tools that ensure a full stack developer can
