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 obj = [...Array(1000).keys()].reduce((acc, i) => {
const key = String.fromCharCode('a'.charCodeAt(0) + ((i / (26 * 26)) % 26)) + String.fromCharCode('a'.charCodeAt(0) + ((i / 26) % 26)) + String.fromCharCode('a'.charCodeAt(0) + (i % 26));
acc[key] = i;
return acc;
}, {});
Ready to run.
