The MEAN stack is a full-stack JavaScript framework used for building modern web applications. It leverages the power of MongoDB, Express.js, Angular, and Node.js to create efficient, scalable, and maintainable applications.

Key Components of the MEAN Stack:

• MongoDB: A NoSQL database that stores data in a flexible, JSON-like format, providing scalability and high performance for handling large volumes of data.
• Express.js: A lightweight web application framework for Node.js that simplifies the development of server-side applications and APIs, providing features for routing, middleware, and template engines.
• Angular (or AngularJS): A front-end JavaScript framework for building dynamic single-page applications (SPAs) with a modular and reusable component-based architecture.
• Node.js: A server-side JavaScript runtime environment that executes JavaScript code outside the web browser, enabling developers to build fast and scalable server-side applications.
