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:

Comparison study for how an MVC framework vs. jQuery vs. native code performs while rendering a list populated from an array. We're doing a study trying to determine the best JavaScript approach to an app running on an ARM board, so we want to get a sense of what we're sacrificing in native js vs. jquery-only vs. angular.js scenarios.
<!-- Jquery -->
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
jQuery:
<div id="jq_test"></div>
<script>
var jqEl = $('#jq_test');
var children = '';
var jqPush = function (data) {
children += '<span>' + data + '</span>';
}
var jqRender = function () {
jqEl.append(children);
//jqEl.append('<span>' + data + '</span>');
}
var jqClear = function () {
jqEl.empty();
children = '';
// not sure if we need to do more to prevent memory leak - probably doesn't matter
}
</script>
<!-- Angular -->
<div ng-app>
Angular:
<div ng-controller="Ctrl" id="angList"><span ng-repeat="item in data">{{item}}</span></div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.3/angular.min.js"></script>
<script>
var Ctrl = function($scope){
$scope.data = [];
}
angular.element(document).ready(function() {
var angScope = $('#angList').scope();
window.angularClear = function(){
angScope.data.splice(0, angScope.data.length);
// angScope.$digest();
};
window.angularPush = function(data){
angScope.data.push(data);
// angScope.$digest();
};
window.angularApply = function(data){
angScope.$apply();
};
});
</script>
Ready to run.
