Angular VS Knockout VS Ember

JavaScript performance comparison

Revision 100 of this test case created by thelinuxlich

Info

I saw an unfair comparison between Angular, Knockout, ExtJS, and Backbone, and it made me mad. So I created this one.

Preparation code

<!-- Jquery -->
<script src="http://code.jquery.com/jquery-1.7.2.min.js">
</script>
<!-- Angular -->
<div ng-app>
  Angular:
  <span ng-controller="Ctrl" id="angList">
    <span ng-repeat="item in data">
      {{item}}
    </span>
  </span>
</div>
<script src="http://code.angularjs.org/1.1.3/angular.js">
</script>
<script>
  var Ctrl = function($scope) {
      $scope.data = [];
      }            
     
  angular.element(document).ready(function() {
    var ang_scope = $('#angList').scope();
    window.ANGDigest = function() {
      $('#angList').scope().$digest();
    };
    window.ANGclear = function() {
      ang_scope.data.splice(0, ang_scope.data.length);
    };
    window.ANGpush = function(data) {
      ang_scope.data.push(data);
    };
  });
</script>
<!-- Knockout -->
<div id="koapp">
  Knockout:
  <span data-bind="repeat: {foreach: data}">
    <span data-bind="text: $item"></span>
  </span>
</div>
<script src="http://knockoutjs.com/downloads/knockout-2.2.1.js"></script>
<script src="https://raw.github.com/mbest/knockout-repeat/master/knockout-repeat.js">
<script src="https://raw.github.com/mbest/knockout-deferred-updates/master/knockout-deferred-updates.js"></script>
</script>
<script>
  var KOData = ko.observableArray();
  var KOviewmodel = {
    data: KOData
  };

  ko.applyBindings(KOviewmodel, document.getElementById('koapp'));
  var KOclear = function() {
      KOData.splice(0, KOData().length);
      };
  var KOpush = function(data) {
      KOData.push(data);
      };
</script>
<!-- Ember -->
<div id="emapp">
  Ember:
  <script type="text/x-handlebars">
    < span > {
      {#each EMapp.data
      }
    } < span > {
      {
        this
      }
    } < /span>{{/each
    }
    } < /span>
  </script>
</div>
<script>
  var ENV = {
    EXTEND_PROTOTYPES: false
  };
</script>
<script src="https://github.com/downloads/emberjs/ember.js/ember-0.9.8.1.min.js">
</script>
<script>
  EMapp = Ember.Application.create({
    rootElement: $('#emapp')
  });
  EMapp.data = Ember.A();

  EMclear = function() {
    EMapp.data.clear();
  };
  EMpush = function(data) {
    EMapp.data.pushObject(data);
  };
</script>
