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
let arr = [];
let obj = {};
let ids = [];
for (let i=0; i<1000; i++) {
let letter = String.fromCharCode(i%26 + 65);
let letterCount = Math.floor(i/26) + 1;
let id = letter.repeat(letterCount);
let entity = {id, value: id};
arr[i] = entity;
obj[id] = entity;
if (i % 100 === 0) {
ids.push(id);
}
}
arr = [];
obj = {};
ids = [];
Ready to run.
