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
<div id="adiv">
<p id="innerp">p elem</p>
<span id="innerspan">span elem</span>

<script>
function rChild() {
var oldE = document.getElementById("innerspan");
var newE = document.createElement("p");
oldE.parentNode.replaceChild(newE, oldE);
}
function raChild() {
var oldE = document.getElementById("innerspan");
var newE = document.createElement("p");
oldE.parentNode.removeChild(oldE);
oldE.parentNode.appendChild(newE);
}
</script>
Ready to run.
