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:

if ((x | 0) < 3) return 1;
return ((fibLikeAsm((x - 2) | 0) | 0) + (fibLikeAsm((x - 1) | 0) | 0)) | 0;

Ready to run.
