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
<script>
function times(n){ return Array(n+1).join('0').split('0') }
var arr = [], k = 64
times(1e2).forEach(function(n){ arr.push(n); })
</script>
Ready to run.
