BACKGROUND OF ANGULARJS

AngularJS is now a product by Google. It is further developed and maintained by Google Engineers. Because the brand behind AngularJS is Google, it is undoubtedly the best framework for web development. It offers two way binding process that allows flexibility in views. And it comes with MVVM model that makes development very interesting.

AngularJS is a development technology that gives importance to modern browsers and fasterThe features are data binding, controllers and deep linking, form validation, communication with server, directive and localization.

THE MODELS OF ARCHITECTURE IN ANGULARJS

MVVM DESIGN PATTERNS

This is an evolved version of MVM design model. In the model, view is completely separate from the models. The view is aware of the model. The logic is stored in the presenter. In the model, the view is the active aspect and identifies with elements like behaviors, events and data binding. Here, the view model takes care of the presentation of separation and guides methods in order to manage the state of the views. The latest version of AngularJS i.e. Angular2 comes with MVVM structure. Updating to Angular2 can be helpful in optimizing the performance of the web application. It can help the developers in faster development process. 

MVC

It defines the communication between the objects. It is a model that is selected by many JavaScript based technologies as architecture for a creating web application. The model is the data and the view represents the data in the front end. The three types of objectives are separated by abstract boundaries.

THE FEATURES

TWO WAY BINDING

Two Way Binding process, the coding becomes lesser. It allows manipulation of DOM elements and attributes. This process offers good sync between the model and the view where any changes made to the model will be updated to the view and likewise changes made in the view will be updated to the model.

UNIT TESTING

The dependency injection is included in AngularJS technology which lets the developer manage the controllers. In the DI, the controllers are relied upon the DI to communication information to objects. And thus, manipulation of DI is possible where it performs testing by injecting mock data into the controller to the see the behavior and measure the output.
