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
Fine tuning the DOM method to yield better performance for this particular synthetic test. (alternate method without cloning)
<div id="main_node"></div>
<script>
var parent = document.getElementById('main_node'),
fragment = document.createDocumentFragment();
</script>
document.getElementById('main_node').innerHTML = '';
var innerHTMLDOM = '<div>';
for (var i=0; i<1000; i++) {
innerHTMLDOM += '<div></div>';
}
innerHTMLDOM += '</div>';
document.getElementById('main_node').innerHTML = '';
Ready to run.
