Angular VS Knockout VS Ember

JavaScript performance comparison

Revision 39 of this test case created

Info

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

This version uses angular 1.2, knockout 2.1.0 and ember-1.0.0-pre.2

Preparation code

<!-- Jquery -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.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://ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"></script>

<script>
  var Ctrl = function($scope){
    $scope.data = [];
  }
 
  angular.element(document).ready(function() {
    var ang_scope = $('#angList').scope();
   
    window.ANGclear = function(){
      ang_scope.data.splice(0, ang_scope.data.length);
      ang_scope.$digest();
    };
    window.ANGpush = function(data){
      ang_scope.data.push(data);
      ang_scope.$digest();
    };
  });
</script>



<!-- Knockout -->
<div id="koapp">
  Knockout:
  <span data-bind="foreach: data"><span data-bind="text: $data"></span></span>
</div>

<script src="http://cdnjs.cloudflare.com/ajax/libs/knockout/2.1.0/knockout-min.js"></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/wycats/handlebars.js/handlebars-1.0.rc.1.js"></script>
<script src="https://github.com/downloads/emberjs/ember.js/ember-1.0.0-pre.2.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>

<!-- Poko -->
<div id="poapp">
  POKO:
  <span data-poko="template: {foreach: .data}"><span data-poko-tpl="text: .value"></span></span>
</div>

<script src="http://www.liqua.com.au/js/poko.js"></script>

<script>
  var POData = {data:[]};
  var poko_props = poko(POData);
 
  jQuery("#poapp [data-poko]").poko({attr:"data-poko", data:POData});
  window.POclear = function (){
    POData.data.clear();
  };
  window.POpush = function (data){
    POData.data.push(data);
  };
</script>

Preparation code output

Angular: {{item}}

This is a terrible test though. You aren't even doing angular properly. http://jsperf.com/angularjs-vs-knockoutjs/3 for a real test
