MEAN represents four software components that are utilized in the back-end also as within the front-end development. As MEAN may be a JavaScript software stack, all the components are supported JavaScript that delivers flexibility and simple development. MongoDB is free and an open-source NoSQL database program that's wont to create a scalable base and with flexible components. Express JS may be a JavaScript web application framework to create dynamic websites with efficient features. Express JS and NodeJS both are used as a server-side framework to deliver unmatched performance in web applications. Node JS is an open-source and cross-platform web development framework that's wont to build scalable web applications. It supports rich JavaScript modules and libraries. AngularJS is mentioned as a client-side framework and is employed in front-end web development with high efficiency and potentially to develop high-end web applications. MEAN STACK is very favorable in future programming with Full-stack JavaScript development where technology drives easier and simpler ways to create feature-rich applications. it's simpler, reliable, and versatile for the dynamic website and mobile applications. The simpler, yet robust structure of MEAN STACK delivers a well-ordered mechanism for the transformation of knowledge . Hence, the structure of MEAN STACK is more suitable and well defined so as to take care of the dynamic performance of the web site and mobile app.
