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
var list = Array(1000).fill().map(() => ({id: Math.floor(Math.random() * 100000)}))
var obj = list.reduce((acc, curr) => ({
...acc,
[curr.id]: curr
}),{})
Ready to run.
