I'm having trouble with the code for logging the rendered info into the console.

Bit confused on the last part of the task. Thanks for help.

app.js 
angular.module('myApp', [])
.controller('myController', function($scope) {
  $scope.user = {
    name: 'Alex'
  };
})
.directive('myDirective', function () {
  return {
    require: 'ngModel',
    priority: 1,
    link: function ($scope, $element, $attrs, ngModelCtrl) {

      ngModelCtrl.$render=function() {
          var contents = ngModelCtrl.$viewvalue;
          console.log(contents);
      };
    }
  }
});
index.html 
<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <title>Angular.js</title>
  <script src="js/angular.js"></script>
  <script src="app.js"></script>
</head>
<body ng-controller="myController">

  <p>Hello {{user.name}}</p>
  <input type="text" ng-model="user.name" />
  <div my-directive ng-model="user.name"></div>

</body>
</html>

All worked out now! $viewvalue should be $viewValue. Classic blunder

Yes you have to watch those common typing errors. $viewvalue !== $viewValue
