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
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<div data-foo="bar" class="foo"></div>
<script>
var elm = $("div.foo"),
result = null;
function hasClass(elm, class) {
var className = " " + class + " ";
return ((" " + elm.className + " ").replace(/[\n\t\r]/g, " ").indexOf(className) > -1);
}
</script>
Ready to run.
