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 regex1 = /beginning/,
regex2 = /(end of).*(end)/,
regex3 = /beginnizg/;
var simpleWrapper = function (regex, string) {
string.search(regex) > -1;
};
</script>
Ready to run.
