AngularJS is a popular client side MVC and MVVM Javascript library used for creating Single Page Application.
Starting an Empty Web Site Project in Visual Studio 2015 and adding Nuget packages for AngularJS Core and Routing.
Though AngularJs can be developed using any Text Editor I prefer using Visual Studio which also provides intellisense for AngularJS.
$scope Service
In AngularJS whatever starts with $ is a service. $scope service is equivalent to ViewBag in Asp .Net MVC. It is the glue between Controller and View. $scope supports two way data binding.
Modules
Modules are equivalent to namespace in .Net.
Here I am defining a Module named Contacts which contains a controller named HomeCtrl. Inside the controller I an array of Names and passing it to View.
