Example
Module serves as a container of different parts of your app such as controllers, services, filters, directives, etc. Modules can be referenced by other modules through Angular's dependency injection mechanism.
Creating a module:
angular
.module('app', []);
Array [] passed in above example is the list of modules app depends on, if there are no dependencies then we pass Empty Array i.e. [].
Injecting a module as a dependency of another module:
angular.module('app', [
'app.auth',
'app.dashboard'
]);
Referencing a module:
angular
.module('app');
