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 alpha = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'];
const vars = [
Array.from({length: 10}, () => alpha[Math.floor(Math.random() * 26)]).join(''),
Array.from({length: 20}, () => alpha[Math.floor(Math.random() * 26)]).join(''),
Array.from({length: 40}, () => alpha[Math.floor(Math.random() * 26)]).join(''),
Array.from({length: 80}, () => alpha[Math.floor(Math.random() * 26)]).join('')
];
const getRnd = () => vars[Math.floor(Math.random() * (vars.length - 1))]
Ready to run.
