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
test = [...Array(100_000)].map(e=>~~(Math.random()*10))
test.map(num => num % 2 === 1 ? [2, 2] : 1).flat()
const fn = num => num % 2 === 1 ? [2, 2] : 1
Ready to run.
