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">This is an element with <code>id="foo"</code>.</p>
<script>
function gEBI(id) {
return document.getElementById(id);
};
var qGEBI = document.getElementById.bind(document);
var $nodes = {}; // will be used by $qmemo()
function $memo(id) {
return $nodes[id] ? $nodes[id] : $nodes[id] = qGEBI(id);
};
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
