Very Simple Example: https://ngcourse-1.rangle.io/handout/03-javascript/index.html
angular.module('ngcourse')
.controller('MainCtrl', function($scope) {
$scope.username = 'alice';
$scope.numberOfTasks = 0;
});
This code defines an AngularJS controller called MainCtrl as a part of a module ngcourse. The way it does it may seem counterintuitive at first.
