Top MERN Technologies- Every Fresher Should Know
Excerpts from: https://careers.relinns.com
MERN stack technologies have become an integral part of the IT world. Developers use them to develop cloud-based, JSON-heavy apps that need dynamic web interfaces. You can build news aggregation sites, workflow management solutions, calendars, to-do apps, and interactive forums or social networking platforms.
Keeping the things, it is not wrong to say that MERN stack developers are undoubtedly in demand. You can also be one of them!
What is a MERN stack?
MERN stands for MongoDB, Express JS, React JS, and Node JS and allows a developer to construct a three-tier architecture using just JavaScript and JSON.
MongoDB (Runs on any Platform)
MongoDB is a document-oriented NoSQL database program that is popular for its flexibility and scalability and is capable of meeting the most detailed requirements.
Another remarkable point of MongoDB is that it has a huge capacity for high-volume data storage and provides developers with numerous drivers in several languages.
React (Front end development)
This declarative JavaScript framework is used for creating dynamic client-side apps in Hypertext Markup Language.
A MERN stack developer can build complex interfaces through simple components, connect them to data on their backend server and render them as Hypertext Markup Language.
Node JS (JS Runtime Environment)
Node JS lets a MERN stack developer execute JavaScript code outside a web browser. This makes it easy for them to develop fast and scalable server-side web applications.
Express JS (Back-end framework)
Express JS is a backend framework within Node JS and lets a developer design and build single, multi, or hybrid web applications.
What are the top 8 Web Technologies every fresher should know?
1. Hypertext Markup Language
A MERN stack developer should have a good command of Hypertext Markup Language as it helps them make their websites appear more appealing.
A developer uses Hypertext Markup Language to instruct a web browser on how and where to place every element on a page.
Besides helping with the page layout, it lets a MERN stack developer give proper instructions regarding graphics, tables, titles, colors, fonts, and headings.
2. Cascading Style Sheets
"Cascading Style Sheets" lets a MERN stack developer assign the proper color combination to their webpage's various elements (text, buttons, tables, etc.)
Thus, as a MERN stack developer, you must know how to work with CSS to segregate formatting and content.
Doing so ensures that your web pages will be compatible with different screen sizes and devices.
3. JavaScript
Dynamic websites excite people more than static ones.
As a result, you must also know how to code your web pages' behavior (that is, render them more interactive and dynamic) using JavaScript.
This means that now you can include button colors, videos, slideshows, audio, animations, etc., in your websites.
4. Visual Studio VS code
Stack Overflow states that around 70% of professional web developers use Visual Studio code, bestowing on it the title of "the most popular developer environment tool."
Web developers cherish Visual Studio VS code, for it lets them add extensions to customize their apps and can be used with an array of programming languages.
Apart from this, VS code simplifies the coding process and helps immensely with removing potential bugs and errors with the help of its built-in debugging and syntax highlighting.
Thus, a MERN stack developer must recognize the importance of Visual Studio Code.
5. Git
As a MERN stack developer, you will be required to experiment with your code in order to enhance your application's functionality.
While doing so, you might encounter a slew of errors, making you want to go to the previous sound version of your piece of code.
It is made possible with the availability of several versions of control systems, and Git is one of them.
The reasons for Git being MERN stack developers' first choice are that it is scalable, free, fast, and decentralized.
Also, it lets two MERN stack developers work on the same piece of code simultaneously without overriding each other.
6. Sass
A MERN stack developer needs to know how to use Sass. Sass stands for syntactically Awesome Stylesheet and is one of the CSS pre-processors used to simplify the process of eliminating repetition and adoring a website.
It is popular among the masses because it adds several features to Cascading Style Sheets, such as inheritance, imports, variables, nested rules, and built-in functions.
Thus, those dabbling in MERN technologies must learn all about Saas as it is a well-supported, reliable, and potent CSS pre-processor.
7. Bootstrap
Bootstrap and JavaScript templates let a MERN stack developer quickly design and customize responsive websites.
The Bootstrap framework is a MERN stack developer's go-to framework, showing that 22% of all websites use Bootstrap today.
Therefore, you should work on your knowledge of Bootstrap before sitting for an interview.
8. SQL
SQL (Structured Query Language) is a standard language for managing and manipulating relational databases.
While MongoDB is the primary database in the MERN stack, having a basic understanding of SQL gives developers an edge, especially when working on projects that require integration with relational databases or migrating data.
In fact, many companies rely on SQL databases like MySQL or PostgreSQL for critical operations. Therefore, you should strengthen your fundamentals in SQL to broaden your skill set and showcase your versatility during interviews.
Salary & Job Opportunities for Freshers
The demand for MERN stack developers has grown rapidly with the rise of full-stack web applications. Freshers trained in MERN technologies can land roles such as Junior Web Developer, Frontend Developer, Backend Developer, Full Stack Developer, PHP Developer. Start-ups, tech companies, and even established MNCs are actively hiring MERN-skilled candidates.
In India, the average starting salary for a MERN stack fresher typically ranges from ₹1.5 to ₹6 LPA, depending on location, skills, and the hiring company.
Conclusion:
Remember: ‘every expert was once a beginner’. If you’re a fresher dreaming of becoming a skilled MERN stack developer, you’re already on the right track. Joining a good training institute can be a game-changer. A structured training program will not only help you master each component of the MERN stack but also equip you with hands-on project experience, best industry practices, and the confidence to crack interviews for internships and junior developer roles.
