The Model-View-Controller Architecture
The model-view-controller architecture, commonly called MVC, of AngularJS is just perfect.
MVC, in simple terms, is the software design pattern that is used to develop applications. M of MVC, which is called Model, is used to handle the data, V of MVC, referred as View, is responsible of displaying and managing view objects, and C of MVC, which is Controller, has a duty to play an intermediary role between the Model and the View.
In normal applications, which you apply MVC design pattern, you have to split your application in to these three camps and then add code to it.
After that, you have to connect all of them. In AngularJS, you just need to split your application into three camp, all the rest of the connections will be handled by AngularJS itself.
That is one of the main reasons why AngularJS is popular and is considered to be the spine of Front-End web development. The figure down below shows the general architecture of MVC.
Less Code but more Efficient
AngularJS needs much less coding than the other front-end web development frameworks. As mentioned above that you do not have to connect the MVC layers, you don’t have to write separate codes for the view manually etc.
Collectively, all of these features of AngularJS save a lot of valuable time of web developers.
State of the art Unit Testing Module
Debugging and Unit Testing is kind of the backbone for the success of any software or application. Angularjs provides unit testing technique that helps the developers produce the high quality applications.
The code may be divided into the small testable parts called units. This helps the developers to debug their code more efficiently and remove bugs from it.
