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
<script>
var arr = (function() {
var i = -1,
length = 10000,
ret = Array(length);
while (++i < length) {
ret[i] = i;
}
return ret;
})();
</script>
Ready to run.
