Question

Answer 1

You need to register your controller with the main module of your application.

Try this in your app.js

 var myApp = angular.module('app', []);
 myApp.controller('mainController', function($scope){
    $scope.message = "Plunker";     
 });

and in your html

    
        
        
        
    

    
        
Hello {{ message }}
