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
Manual array lookups vs. holey arrays.
var a1=[];
var a2={};
for (i=0; i<2000; i++) {
a1[i]=i;
a2[i]=i;
}
Ready to run.
