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
Building the HTML as one big string, then adding it in one single .append() call. Also increased 'count' to 20 to make the difference more noticeable.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<div id="mydiv" style="display:none"></div>
<script>
var html = "<div>some<span>things</span><br>never<div>change</div></div>";
var count = 20;
function cleanup() {
$("#mydiv").html("");
}
</script>
cleanup();
Ready to run.
