What is MEAN-stack?

Various technologies are used in the web development process. These include web servers, libraries, front-end frameworks, and database systems. Developers use a strategy of using a combination of such tools and technologies to speed up and improve the efficiency of the web development process.

For example, MEAN-stack. This is an acronym for MongoDB (database system), Express (back-end web environment), Angular.js (front-end framework), and Node.js (back-end runtime). These technologies were developed at different times. But today they are grouped together to form a MEAN stack, and the reason is pretty clear. JavaScript connects them. JavaScript is a dynamic programming language for developing client-side and server-side web applications.
