● It facilitates development by utilizing the model view controller (MVC) architecture.

● Developers must be familiar with JavaScript and JSON to use this JavaScript stack.

● Developers may utilize React code on both web browsers and servers. This JS stack enables the creation of pages on the server as necessary.


The Curve of Learning

Node.js, MongoDB, and Express.js are all extremely popular technologies with extensive documentation. The learning curves for MEAN and MERN appear to be identical. Nonetheless, the learning curve for React and Angular will differ.

Angular is a template and typescript framework. You may discover that Angular has a higher learning curve, but React does not.


Given that both MERN and MEAN stacks use Node.js, Express.js, and MongoDB, a profitability comparison between the two would indicate a preference for React over Angular.

Because Angular is a comprehensive framework, it offers increased profitability. Generally, you would utilize third-party React libraries that give lower designer productivity.

Angular has a CLI (Command Line Interface), which increases designer productivity. And when you rethink your code, you’ll see how much easier the Angular CLI makes it. Due to the availability of third-party libraries, maintaining your React code requires more effort.

Flow of Data

In the case of Angular, the data flow is bidirectional, which means that if you change the UI, the model state is instantly updated. The data flow in React is unidirectional. Thus, you may modify the user interface only after modifying the model state if you utilize React.

React’s unidirectional data binding provides a greater perspective of the data, which aids in managing big projects. As a result, the MERN stack is more suited to large-scale projects.

Angular’s bidirectional data binding becomes the more efficient option if you’re working on a small project. MEAN stack comes very handy here!

Support from a Third Party

Utilizing third-party libraries is another excellent consideration when developing enterprise-level applications. MEAN includes Angular, which includes built-in capabilities for HTTP call support and back-end integration.

Nonetheless, ReactJS provides several complementary frameworks for implementing comparable features. MEAN offers plug-and-play support for third-party extensions, whereas MERN requires different settings to do the same thing.

Code Management and Updates

With the added benefit of Angular, the MEAN stack simplifies code management and upgrades. Angular, being a well-organized and comprehensive framework, can aid the MVC design more effectively.

You may quickly isolate database-related code from UI-related code by implementing an intermediary layer that simplifies code management and upgrades. Due to the inclusion of third-party libraries, managing and upgrading React code requires extra effort.

Development of mobile apps

Angular provides the ionic framework for the development of mobile applications. It allows you to develop hybrid mobile apps. Because these applications use a single codebase for both iOS and Android, development costs are minimized. Hybrid apps, however, have reduced the native user experience.

React Native differs slightly in this regard. It delivers a near-native user experience; as a result, you may discover that the MERN stack is a superior choice for mobile application development.

Angular application testers have a unique experience compared to React application testers. It will generally affect your choice between the MEAN and MERN stacks. You can test an Angular app fast with only one tool, such as Jasmine.

It’s not the case, however, with a React application, where several technologies will require. You’ll need to test the JS code with a tool like Jest, while the elements may require testing with something like Enzyme. When developing a React application, you’re likely to use many third-party libraries; hence, your testing effort is amazing.

Flexibility and Security

MERN and MEAN stacks both offer industry-leading security. As a consequence, you can choose one.

However, MERN is more secure than MEAN because it is more scalable.

Applications on a Large Scale

If you’re developing an eCommerce-related application, the MEAN stack is an excellent choice. It can serve as the foundation for dynamic web applications and facilitate the development of prototypes. I propose MEAN stack as a full-stack development platform for creating large-scale projects.

User Interface Requirements

Do you want a straightforward yet sophisticated UI rendering for your application? Then, proceed to the MERN stack to do this. It can instantly generate a frame and display it on the screen, ensuring a consistent user experience.

Development Team Expertise and Experience

Supporting documentation is not critical if your development staff is extremely knowledgeable and experienced with web frameworks. The learning curve in this scenario is less steep; therefore, you may select the MEAN stack.

If your development team has a modest degree of expertise, you must consider the learning curve, which is why the MERN stack is a better choice.

MVC Support

If you’re developing an enterprise-level application, you’ll need to keep to a comprehensive architecture. It is why you should select the MEAN stack rather than the MERN stack. More information about the MERN Stack course is at the MERN Stack Online Course

By selecting this, you’ll have access to the Model-View-Controller architecture’s support. You can, however, use the MEAN stack if your code is simple to handle.

CRUD Applications

The MERN stack enables you to quickly design and develops CRUD (Create, Read, Update, and Delete) applications from start to finish.

The use of React ensures that data changes are handled quickly and that the user interface is excellent. MERN is an excellent framework for developing mobile apps or single-page applications.

Error Prevention

If you’re looking for a stack to prevent fundamental coding errors, the MEAN stack is your best bet. Angular makes use of Typescripts, a framework that helps minimize common code errors throughout the development phase.

Improving and Maintaining the Long-Term

React and Angular are both extremely popular frameworks. However, React is growing in popularity, and hiring React developers will become more accessible in the future.

Consider utilizing the MERN stack if your application has a substantial upgrade pipeline, and you may anticipate considerable long-term maintenance requirements.


The MEAN stack uses Angular, which maintains the DOM current (Document Object Model). The DOM provides access to XML and HTML documents through a programming interface.

By contrast, MERN makes use of React to keep the virtual DOM updated. As a result, MERN enables faster application development.

As a result, no framework will ever be able to address all business objectives. To achieve a better outcome and fulfill your company goals, you must research each feature, match them to the rapid development requirements, and pick carefully.
