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
function randomString()
{
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
for( var i=0; i < 5; i++ )
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
var preComputedRandomKeys = [];
var preComputedRandomVals = [];
for (var i=0; i < 10000; i++) {
preComputedRandomKeys[i] = randomString();
preComputedRandomVals[i] = randomString();
}
var item_activityProperties = {};
for (var i=0; i < 10000; i++) {
item_activityProperties[preComputedRandomKeys[i]] = preComputedRandomVals[i];
}
console.log(item_activityProperties)
