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>
Hello world!
</div>
<script>
var div = document.getElementsByTagName("DIV")[0];
// Vary width each time so is actually doing something
var oddValue = 'Value for when count is odd';
var evenValue = 'Value for even';
var count = 0;
var changeValue = function () {
div.nodeValue = count%2 ? oddValue : evenValue;
count++;
};
</script>
Ready to run.
