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 0 = {};
for (var i=0;i<33000;++i){
a1.push({id:i, name:"name1"});
o[i] = {id:i, name:"name1"};
}
var a2 = [];
a2[29938] = {id: 29938, name: 'name1'};
a2[32994] = {id: 32994, name: 'name1'};
var o = {};
o['29938'] = {id: 29938, name: 'name1'};
o['32994'] = {id: 32994, name: 'name1'};
Ready to run.
