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
window.mySet = new Set();
window.myArr = [];
for (let i = 0; i < 1000000; i++) {
window.mySet.add(i);
window.myArr.push(i);
}
window.results = []
window.results.length = 0;
Ready to run.
