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 id = () => (Math.random() + 1).toString(36).substring(2);
const count = 300;
const arr = Array(count).fill().map(id);
const set = new Set(arr);
// Create an agenda of 50 IDs that exist in the set,
// and 50 that don't.
const toFind = [
...arr.slice(0, count/2),
...Array(count/2).fill().map(id)
]
Ready to run.
