Delivers a Great Structure for Your Application:
Data Binding from Both Sides:
Data binding is one of the best functionalities offered by AngularJS. It becomes possible for you to bind your modules to HTML elements. With the change in the model, the view gets updated automatically and vice versa. This brings down the amount of boilerplate code usually written to sync the model and view.
Using AngularJS directives you can teach HTML new syntax. It lets you create reusable personalized components with the help of directive API. For instance, if you wish to create a custom date picker widget you can use a <data-picker/> component. If you wish to get a fancy file uploader using progress indicator you can create a <file-upload/>component.
Templating using HTML:
AngularJS utilize HTML for templating. This ensures simplicity and enables designers as well as programmers to work in sync. Designers can create UIs in the normal way and developers can use declarative binding syntax to bind different UI components using data models.
Embeddable, Injectable, and Testable:
AngularJS serves as an excellent team player. It doesn't demand commitment. As per the official website of AngularJS- You can use as much or as little of AngularJS as you require. If you need a single feature of it, then you can do that.
AngularJS provides Dependency Injection. If you require something, then you may ask Angular to inject it. This enhances the testability levels as it becomes convenient to mock the components while testing. The main aim of creating AngularJS was testability. Unit testing becomes much easier with modules and dependency Injection system. Additionally, AngularJS offers Protractor, which eases End-to-End testing. The code you write is testable as well as maintainable.
The above are not the only features which make AngularJS a programmer-friendly code; a number of other features such as routing, filters, and animations are make AngularJS quintessential.
