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 = [], o = {}, a2=null;
for( i=0; i <=2; i ++){
a1.push( { id: i, name: 'name' });
o["i"] = { id: i, name: 'name' };
}
Ready to run.
