**Do you find yourself awestruck by the stunning websites that emerge in front of you?** 
Those were created by Full-Stack Developers. Full-Stack Developers are the most in-demand professionals and will always be in high demand. MERN is an extremely demanding full-stack technology. It is the most widely used way of creating a website. MERN stack developers number in the millions worldwide.

MERN's website is built with MongoDB, Express, ReactJS, and NodeJS.

1. MongoDB – A document-oriented NoSQL database whose data storage format is BSON.
2. Express – A web application framework for NodeJS.
3. ReactJS – A JavaScript library for building User Interfaces.
NodeJS – An open-source, cross-platform JavaScript run-time environment that helps in developing tools, applications, and servers.

**How Do You Begin as a Beginner?**

If you're a newbie and a tech enthusiast looking to create full-stack projects, you've come to the correct place. Your trip begins with HTML and CSS, which serve as the backbone of an application. Begin with simple tasks like a calculator, a survey form, and a simple website. You'll develop confidence and a desire to build something bigger and more intriguing as a result of this. When you reach this point in your life, you are ready to become a MERN Stack Developer.

The nicest part about using MERN to construct an application is that both technologies can only function with one programming language, JavaScript. JavaScript can be used to create both the backend and the frontend. Because JavaScript is one of the most popular programming languages and is simple to learn, it is important to have a solid understanding of it as well as hands-on experience with it. Also, regardless of technical background, anyone can become a MERN Stack developer. All you need is the will to become one.

**MERN Stack Developer Technology Requirements**

**1. MongoDB**

Dwight Merriman, Eliot Horowitz, and Kevin Ryan founded MongoDB in 2007. MongoDB is a NoSQL database that is open-source and document-oriented. Its data storage format is BSON (Binary _[JavaScript Object Notation). [mongoDB tutorial](https://www.geeksforgeeks.org/mongodb-tutorial/) This can assist you in covering fundamental to advanced MongoDB topics such as the

 
1. MongoDB setup,
2. MongoDB methods (Insert(), Update(), Find(), count(), skip(), and so on).
3. Operators (Logical, Arithmetic, Relational, Expression) (Logical, Arithmetic, Relational, Expression),
4. When it comes to working with documents and collections,
5. Creating MongoDB Projects

**2. ExpressJS**

TJ Holowaychuk pioneered the use of Express.js. ExpressJS is a web application framework that allows you to create web and mobile apps. Express allows you to create single-page, multipage, and hybrid web applications. If you are a beginner and wish to construct an application with Express, please read [steps to create Express.js Applicacation](https://www.geeksforgeeks.org/steps-to-create-an-express-js-application/)This is a well-defined method that describes the commands to install various packages, the file structure, and the procedures required to launch the application.

**3. ReactJS**

Jordan Walke designed React, a JavaScript library for creating user interfaces. It is used to construct single-page applications and reusable UI components. According to a reputable source, almost 8700 businesses use React, with Uber, Instagram, Netflix, Airbnb, Twitter, and Reddit being among the most popular. The react community is massive and continues to develop daily.
[ReactJS](https://practice.geeksforgeeks.org/courses/react-course?utm_source=article&utm_medium=article&utm_campaign=react-course)covers common React concepts such as states, React Hooks, Event Handling, Redux, and deploying a project to see it in action.

**4. NodeJS**

NodeJS is a JavaScript runtime based on the V8 engine in Chrome. It is a non-blocking, event-driven server that is used to create webpages and back-end API services. NodeJS can be used to create data-streaming apps, JSON API-based applications, and data-intensive real-time applications (DIRT). Here’s a free resource on [NodeJS](https://www.geeksforgeeks.org/nodejs/) which discusses the basics to advanced usage of it.


**Position Description**
MERN stack is made up of technologies that help to build apps faster. The entire technology is JS-based, making it simple for developers to learn and build projects with it. You may surely start applying to organizations once you have produced outstanding projects and have a thorough knowledge of MERN. But first, you must understand the tasks and responsibilities of a MERN Stack Developer.

**Project Suggestions**

When you begin building projects, you can demonstrate your understanding of MERN. As a beginner, you must begin with the fundamentals before progressing to more complicated projects. Choose an IDE on which to work, a technology such as MERN (HTML, CSS, and JavaScript), and then publish it on GitHub.
