MERN Stack

MERN Stack stands for MongoDB, Express, React, Node.js. It is a full-stack JavaScript framework used to build web applications.

• MongoDB – A database to store data.
• Express – A backend framework to handle requests and routes.
• React – A frontend library to build interactive user interfaces.
• Node.js – A runtime to run JavaScript on the server.

What it can do:

• Build dynamic websites and apps.
• Create full-stack applications with a single language (JavaScript).
• Handle user authentication, data storage, and real-time updates.
• Support REST APIs or GraphQL APIs for frontend-backend communication.

In short: MERN lets you build modern, fast, and scalable web apps using only JavaScript.
