  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;

  &lt;script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"&gt;&lt;/script&gt;

  var app = angular.module('myApp', []);
  app.controller('myCtrl', function($scope) {
      $scope.cars = [
          {model : "Ford Mustang", color : "red"},
