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 p = 'The quick brown fox jumps over the lazy dog. If the dog reacted, was it really lazy?';
// Global flag required when calling replaceAll with regex
const regex = / ([^ ]*) /ig;
function replacer(match) {
return "[" + "a".repeat(match.length - 2) + "]";
};
let a = p;
let b = p;
let c = p;
let d = p;
let e = p;
let f = p;
let g = p;
let dArray = p.split('');
Ready to run.
