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
const arr = Array.from({length: 25}).map((_, i) => (i % 25) + 66 ).reduce((memo, n, i, a) => i === a.length-1 ? memo : ({...memo, [String.fromCharCode(n)]:String.fromCharCode(a[i+1])}), {});
const keys = Object.keys(arr);
Ready to run.
