10 Advantages of using AngularJS

If you doubt you can use it, then don't

23.04.2015

One of the most popular Javascript frameworks for professional web development is AngularJS. It is a Google community powered open source web application platform. AngularJS is a complete solution for rapid front-end development and it's great for single page applications (SPA) and web applications that don’t require anything more than HTML, CSS and JavaScript. AngularJS is well-maintained and robust framework.

If you doubt you can use it, then don't. Here are 10 advantages of using AngularJS.

 

  1. It's unbelievable easy to start!

It's so easy to start working with AngularJS. You just need to add a few attributes to the HTML code and you can start to build your first AngularJS application. There are also so many tutorials that AngularJS provides, so it's a pleasure to work with this framework.

 

  1. It's developed by Google

AngularJS is built by Google engineers. This means that you will have the opportunity to learn from one of the largest open community. If you need help, the dedicated engineers can answer your questions anytime.

 

  1. HTML templates

Angular's templates are written with HTML that contains specific Angular elements and attributes. Angular combines the template with information from the model and controller to render the dynamic view that a user sees in the browser. The input to AngularJS is browser DOM and not an HTML string. Using the DOM allows you to extend the directive vocabulary and build your own directives.

 

  1. MVC implementation

AngularJS implements MVC (Model-View-Controller) by asking to split the application into MVC components, then manages the components and connects them. MVC is made of three components: Model (pattern responsible for maintaining the data), View (responsible for displaying of the data to the user), and Controller (responsible for the interactions between the Model and View). MVC isolates the application logic from the user interface layer and supports separation of concerns.

 

  1. Declarative User Interface

Angular uses HTML to define the application’s user interface. HTML is more elaborate and intuitive language, compared to JavaScript. HTML is used to determine the execution of the app. Special attributes in the HTML determine which controllers to use for each element.

 

  1. Custom directives

Directives can be used to create custom HTML tags and manipulate DOM attributes. By putting all the DOM manipulation code into directives, we can separate them out of the MVC app. This allows the MVC app to concern itself with updating the view with new data. This feature makes it incredibly easy to add, update or delete functionality as needed.

 

  1. Dependency Injection

The dependency injection helps developers by making the application easier to develop, understand, and test. It deals with how components get hold of their dependencies. AngularJS uses the parameter names of controller functions, factories, services and providers to decide what to inject into their factory functions.

 

  1. POJO

Plain JavaScript Objects (POJO) are AngularJS data models. POJO allows to to append or change properties and loop over arrays and objects. Angular’s data models behave more like a cork board and work closely with a controller and view, so you can put and retrieve data. Angular calls these data models “scopes”.

 

  1. Two way data-binding

AngularJS supports two way data-binding. This is one of the most useful features of AngularJS. Data Binding in Angular Templates is the automatic synchronization of data between the model and view components. With data-binding there is no need to write a lot of boilerplate code. The unnecessary code disappears and you can manipulate date using filters without the need for changing the controllers.

 

  1. Testing Option

Testing is a part of every AngularJS tutorial. It's easy to test, so test everything.
