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
Demonstrating the performance hit caused by nested functions.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">

<script>
function a() {
for (var i = 0; i < 10; i++) {
$("body").append("<div>a" + i + "</div>");
}
}
function b() {
var j = "";
for (var i = 0; i < 10; i++) {
j += "<div>a" + i + "</div>";
}
$("#d1").append(j);
}
</script>
Ready to run.
