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 = new Array(100000).fill(0).map(a => ({type:String.fromCharCode(Math.floor(Math.random()*88)+32), data: Math.random()}));
Ready to run.
