1. What is the MERN Stack?

The MERN Stack is a collection of four powerful technologies that work together to create complete web applications. Each part of the stack serves a unique purpose:

• MongoDB: A NoSQL database that stores data in flexible, JSON-like documents.

• Express.js: A backend web framework for building APIs and handling server logic.

• React.js: A frontend library used for building fast and interactive user interfaces.

• Node.js: A JavaScript runtime that allows you to write server-side code using JavaScript.

Together, these technologies allow developers to build dynamic, scalable, and modern web applications entirely using one language — JavaScript.

Example: Websites like Netflix, Uber, and Instagram use technologies similar to MERN for their full-stack applications.

2. Why Learn MERN Stack in 2025?

In 2025, companies are increasingly adopting JavaScript-based technologies for full-stack development. Here’s why learning the MERN stack is a smart move this year:

• High Demand: Thousands of companies hire MERN developers for building interactive web applications.

• Single Language Advantage: You only need to master JavaScript to work on both frontend and backend.

• Faster Development: The stack supports efficient, rapid development with reusable components.

• Career Growth: Full-stack developers often earn higher salaries and have versatile roles.
