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
<output id="out"></output>
let n = 0;
function getStr(){
if( ++n > 1e6 ) return '';
return String(n);
}
n = 0;
document.getElementById('out').value = '';
Ready to run.
