jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
I saw an unfair comparison between Angular, Knockout, ExtJS, and Backbone, and it made me mad. So I created this one.
<!-- Jquery -->
<script src="http://code.jquery.com/jquery-1.11.0.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/1.2.10/angular.min.js"></script>
<script>
/*What we really test here? iterating through array??? is it cheat? ok. */
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){
var data = ang_scope.data.splice(0, ang_scope.data.length);
data.push(data);
ang_scope.data = data;
};
});
</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/3.0.0/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://cdnjs.cloudflare.com/ajax/libs/ember.js/1.3.1/ember.min.js"></script>
<script>
EMapp = Ember.Application.create({
rootElement: $('#emapp')
});
EMapp.data = [];
EMclear = function () {
EMapp.data.splice(0, EMapp.data.length);
};
EMpush = function (data) {
EMapp.data.push(data);
};
</script>
