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 strings = [];
for (var i = 0; i < 500; ++i) {
strings[i] = "The end of the beginning? Or the beginning of the end?";
}
var regexString1 = "beginning",
regexString2 = "(end of).*(end)",
regexString3 = "beginnizg";
var regex1 = new RegExp(regexString1),
regex2 = new RegExp(regexString2),
regex3 = new RegExp(regexString3);
</script>
Ready to run.
