Rise of REST API with Single Page Applications

You need to understand why Single Page Applications (SPA) are the hot topic today. Instead of building the UI in a traditional way (request web pages), these SPA designs make developers write code in a totally different way. There are many MVC frameworks, like AngularJS, Angular2, React JS, Knockout JS, Aurelia, and so on, to develop web UIs rapidly, but the essence of each of them is pretty simple. All MVC frameworks help us to implement one design pattern. That design pattern is No requesting of web pages, only REST API.

The modern web frontend development has advanced a lot since 2010. In order to exploit the features of Model-View-Controller (MVC) architecture, we need to consider the frontend as a separate entity which talks to the backend only using the REST API (most preferably, REST JSON).
