Difference Between MERN Stack, MEAN Stack, and Full Stack Development
Are you someone who are thinking about becoming a web developer? Then we are sure of the fact that you have probably come across terms like:
- MERN Stack Development
- MEAN Stack Development
- Full Stack Development
But as you are JUST starting your journey then they might sound complicated at first, understanding their differences is actually quite simple. So, without much delay let us understand the concepts properly.
What is Full Stack Development?
But before we dive into MEAN and MERN, we need to understand the concept of full stack development.
A website or web application have two main parts:
- Frontend ( A.K.A Client-Side)
This is the part users see and interact with, like buttons, images, and text. Technologies like HTML, CSS, and JavaScript and React.js are used to build it.
- Backend ( A.K.A Server-Side)
This is the part that works behind the scenes, handling data, logic, and user requests. It involves databases, servers, and backend programming languages like Node.js, Python, or PHP.
But who is a full stack developer? What does the professional do?
Mainly, a Full Stack Developer is someone who can work on both the frontend and backend, which means that they can develop an entire web application independently.
Now let us understand MERN stack development:
What exactly is MEAN Stack?
The MEAN Stack is a popular technology stack used for building web applications. It includes:
- M – MongoDB (Database)
- E – Express.js (Backend framework)
- A – Angular (Frontend framework)
- N – Node.js (Runtime environment for JavaScript)
MEAN is a JavaScript-based stack. But what exactly does that mean? Which means both the frontend and backend use the same language. This makes development smoother and easier to manage.
Why Would You Choose the MEAN Stack?
- It is great for large-scale applications, why? Because Angular provides a structured framework.
- Since everything is in JavaScript, developers NO NOT need to learn multiple languages.
- It is scalable and works well for handling large amounts of data.
But this you will need to understand that, Angular has a steeper learning curve compared to other frontend frameworks, which some beginners might find challenging.
Now, let us move to next section that…
What is MERN stack development?
The MERN Stack is very similar to MEAN, but instead of Angular, it uses React for the frontend. The stack includes:
- M – MongoDB (Database)
- E – Express.js (Backend framework)
- R – React (Frontend library)
- N – Node.js (Runtime environment for JavaScript)
Like MEAN, MERN is also JavaScript-based, making it a great choice for developers.
Why Would You Choose the MERN Stack?
- React is easier to learn compared to Angular, making MERN more beginner-friendly.
- It is faster and more flexible, which is perfect for dynamic and interactive web applications.
- Many companies prefer React over Angular due to its efficiency and large community support.
- MERN is widely used in modern web applications, especially for startups and businesses that need fast, responsive, and scalable solutions.
How is Full Stack Development Different?
The term Full Stack Development is broader than MEAN or MERN. A full stack developer can work with any combination of frontend and backend technologies, not just MEAN or MERN.
For example, a full stack developer use:
- Frontend: React, Angular, or Vue.js
- Backend: Node.js, Python (Django), or PHP
- Database: MongoDB, MySQL, or PostgreSQL
This flexibility is why many developers prefer full stack development, as it allows them to work on a variety of projects without being limited to a specific stack.
What is the best way to learn full stack development course?
No matter which path you choose, learning full stack development is a great way to expand your career opportunities. If you are serious about becoming a web developer, consider enrolling in a full stack development course in Kolkata, where you can get hands-on training with industry experts. As you are just starting out in IT,
the demand for full stack developers is increasing rapidly. Whether you choose MEAN, MERN, or another stack, learning both frontend and backend will make you a valuable asset in the job market. All the best!
