Why the MEAN stack?

An obvious question would be why the choice of MongoDB, Node.js, and Express, when we could use any other stack.

To be politically correct, we could use any other technology, such as Java, PHP, ASP.NET, or even Ruby on Rails, to build the backend part of this project, and AngularJS would work just as fine.

The main reason to choose this stack is that all the tools within this stack use a single language, which is JavaScript. Other than this, each of the following tools offers certain unique benefits that make it equally suitable to build this application:

• Node.js: This is the most important tool in this stack. It allows us to build event-driven, nonblocking I/O applications using JavaScript. Thanks to Node.js, we are now able to write server-side applications in JavaScript.

• ExpressJS: This is a lightweight web application framework that allows us to build a server-side application on Node.js using the Model View Controller (MVC) design pattern.

• MongoDB: This is a very...
