In AngularJS the term scope is used as an object, which can be in scope or out of scope itself. The scope is used for the communication between ‘view’ and ‘controller’ and also it behaves as bind or glue.

  1. Validations:

AngularJS has some set of forms and controls which are used to validate the input data. Whenever the invalid data is given as an input, these forms and controls validate and notify to the user. AngularJS Training provides all IT courses which help to get placement in top companies.

  1. Directives:

In AngularJS, DOM (Document Object Model) is accessed only within the directives. If the DOM is want to access directly, you should write the custom directives for DOM access.

  1. Filters:

Filters are used to extend the combination of expressions and directives. Filters are used to access the HTML code when the | (pipe) symbol is used within {{}}. Filters are also used to format the data in DOM.

  1. Controller:

Angular applications are controlled by the controller. The directive ng-controller is used to define the application controller.

  1. Expressions:

Inside the HTML tags, angular expressions can be added and data binding is also done. Before displaying the data angular filters are used.

  1. Routing:

Routing is used to divide the Single Page Applications into multiple views. This process helps to divide the app and make it more manageable.

  1. Services:

Services are like sharing data to the application. Services are also used by others components like filters, controllers, directives.

  1. Modules:

An angular module is a collection of functions in a java script file. An angular module divides the angular app into small and which can be combined in other angular apps. If you want to grab more knowledge on AngularJS, visit AngularJS course in Chennai.
