What is MERN

MERN stack is a popular full-stack JavaScript framework used for building web applications. It consists of the following components:

1. MongoDB: A NoSQL database for storing application data.
2. Express.js: A backend web application framework for Node.js, used for building the server-side of the application.
3. React.js: A JavaScript library for building the user interface and handling the client-side of the application.
4. Node.js: A JavaScript runtime environment that allows developers to run JavaScript on the server-side.

The MERN stack is a powerful and flexible solution for developing modern, single-page applications (SPAs) and other web applications. Here’s a brief overview of how the MERN stack components work together:

• MongoDB: Stores the application data in a flexible, JSON-like document format, making it easy to work with.
• Express.js: Handles the server-side logic, routing, and API endpoints, providing a backend for the application.
• React.js: Manages the user interface, allowing for the creation of dynamic, component-based UIs.
• Node.js: Provides the JavaScript runtime environment for running the Express.js backend and handling server-side logic.

The MERN stack is a popular choice for developers due to its simplicity, efficiency, and the ability to use a single language (JavaScript) for both the client-side and server-side of the application. This can lead to faster development times, easier maintenance, and better code-sharing between the front-end and back-end components of the application.
