1. What is MERN (MongoDB, Express, React, Node)?
The MERN stack is a full-stack JavaScript-based technology suite for building web applications. It includes the following components:
- MongoDB: A NoSQL database that stores JSON-like documents with a flexible schema.
- Express.js: A backend web application framework for Node.js that simplifies server-side logic and routing.
- React: A frontend library known for its component-based architecture and virtual DOM for efficient UI rendering.
- Node.js: A runtime environment for executing server-side JavaScript code.
These technologies work seamlessly together, making MERN a powerful choice for developers aiming to build modern and scalable applications.
