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
<p id="foo">
<span id="bar">This is an element with <code>id="bar"</code>.</span>
</p>
<script>
function $(id) {
return document.getElementById(id);
}
function $u(id,node) {
return (node||document).getElementById(id);
}
Document.prototype.$id = function(id) {
return this.getElementById(id);
}
Element.prototype.$id = function(id) {
return this.getElementById(id);
}
</script>
Ready to run.
