Applications Development with Angular and Node, often referred to as the MEAN Stack, is an approach to building web applications that combines several key technologies: MongoDB (as the database), Express.js (as the backend framework), Angular (for the frontend), and Node.js (as the server-side runtime).

Applications Development with Angular and Node in the MEAN Stack involves utilizing MongoDB for data storage, Express.js for backend development, Angular for building dynamic frontends, and Node.js as the server-side runtime. This technology stack is popular for creating modern, efficient, and scalable web applications.
