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

var s = '';
var spaces = '';
for (var i = 0; i < 36; ++i) spaces += ' ';
for (var i = 0; i < 1000; i++) s += '36\u0000' + spaces;
s.charCodeAt(0);
</script>
Ready to run.
