Angular

Angular provides developers with a wide range of abilities to manipulate the behavior of the elements of a web application’s visual layer, the user interface. Properly implemented, this facilitates a far more dynamic and interactive user experience.

What exactly is Angular?

Angular and AngularJS are front-end web technologies created by Google. They allow you to create complex applications (Single Page Applications) that run on the browser instead of the server. Both frameworks are based on the JavaScript programming language and support the creation of web applications in the MVC architecture (Model, View, Controller). AngularJS was launched in 2009, and its successor Angular in 2016.

Angular is based on TypeScript, which extends JavaScript’s capabilities with static typing. This affords the developer greater control, code manageability, and also shortens the testing period and facilitates the correctness checking. At the same time, the cost of implementing TypeScript is low because JavaScript code is already correct according to TypeScript. From its introduction to the web in 1995, JavaScript’s extreme popularity has grown to establish it as the de facto language of the Internet, upon which all front-end browsers are base. Concurrently, it is increasingly used on the server side to also support back-end functionality (e. g. Node.js).

The advantages of Angular


Abilities

The libraries facilitate many flexible options for exploiting their potential. The MVC design divides the application into three elements, which can be interpreted in several ways.

Minimalism

The library features two-way data binding, thereby requiring less code because Angular itself catches the changes in the model layer and effects the corresponding modifications in HTML code.

Testing support

Testing an app developed with AngularJS has become much easier because the library promotes the aforementioned MCV architecture, further facilitating the integration of unit testing.

Specification

  • The MVW architecture.
    The entire Angular library is on this paradigm (Model-View-Whatever). Angular supports the implementation of a variety of established architectural patterns.
  • Dependency injection
    Another important aspect of Angular is that thanks to it, implemented functionalities in code become more automated.
  • Modules
    These are containers within the layers of our application (controllers, services, directives). A module is a fundamental data storage device, similar to a class, but unable to be instantiated because it is based on slightly different functionality.
  • Two-way data binding
    This is a feature that separates Angular from the other front-end libraries in the pack. This mechanism provides dynamic data synchronization between the view layer and the data model layer.
  • Navigation
    The ability to redirect and interfere in the display of the page view for the appropriate address.
  • Data Filtration
    An indispensable aspect of every application. Angular offers filtering embedded mechanisms that, in sense write their own data filtering functions for the developer.
