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 str = Array.apply(null, Array(100)).map (() => String.fromCharCode(Math.round(Math.random() * 100) % 96 + 32)).join('');
var key = String.fromCharCode(Math.round(Math.random() * 100) % 96 + 32);
Ready to run.
