What is MERN Stack?

MERN = MongoDB + Express.js + React.js + Node.js

Think of it as your all-in-one toolkit to build end-to-end web apps using only JavaScript — from the database to the user interface. Each tech handles a mission:

· 🗃️ MongoDB – stores your app’s data

· ⚙️ Express.js – powers your backend

· 🎨 React.js – builds the UI

· 🚀 Node.js – lets you run JavaScript on the server (fast and scalable apps)

With MERN, you can build cool, cloud-based, mobile-friendly apps — all with one language: JavaScript.

Why MERN Developers Are in High Demand

Companies prefer full-stack developer. They can build everything- from designing front-end UIs to setting up back-end APIs.

Whether it’s a start-up, product-based company, or an IT giant - MERN developers are on every recruiter’s radar.

Top job roles you can grab as a fresher:

🔹Software Engineer

Salary:

In India, freshers with MERN skills earn anywhere between ₹1.5 – ₹6 LPA, depending on city, company, job role & skill level.

10 Web Technologies You Must Learn
