AngularJS Module

In AngularJS, a module defines an application. It is a container for the different parts of your application like controller, services, filters, directives etc.

A module is used as a Main() method. Controller always belongs to a module.


How to create a module

The angular object’s module() method is used to create a module. It is also called AngularJS function angular.module

Here, “myApp” specifies an HTML element in which the application will run.

Now we can add controllers, directives, filters, and more, to AngularJS application.

If you want to add a controller to your application refer to the controller with the ng-controller directive.
