MERN stands for MongoDB, Express.js, React, and Node.js. It is a technology stack used for building full-stack web applications. Here’s a brief overview of each component:
- MongoDB: A NoSQL database that stores data in a flexible, JSON-like format.
- Express.js: A web application framework for Node.js that simplifies the process of building server-side applications and APIs.
- React: A JavaScript library for building user interfaces, particularly for single-page applications, developed by Facebook.
- Node.js: A JavaScript runtime built on Chrome’s V8 engine that allows developers to run JavaScript on the server side.
Together, these technologies enable developers to create robust, dynamic web applications.
