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 SIZE = 10000;
const bigObject = {};
for (let i = 0; i < SIZE; i++) {
bigObject[`key_${i}`] = i;
}
let counter = 0;
Ready to run.
