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 arr = []
const genItem = () => ({ id: Math.random().toString(), title: Math.random().toString(), cp: Math.random().toString() })
for (let i = 0; i < 100_000; i++) {
arr.push(genItem())
}
Ready to run.
