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
After seeing http://jsperf.com/javascript-associative-vs-non-associative-arrays, I thought the test could be improved.
variant of the original test - read only
var arr = [],
i,
obj = {};
for(i = 0; i < 10000; i += 1) {
arr.push(i);
obj[i] = i;
}
function getRandomIndex(obj) {
var idx = Math.floor(Math.random()*9999);
if(false === obj.hasOwnProperty(idx)) {
while (false === obj.hasOwnProperty(idx)) {
idx = Math.floor(Math.random()*9999);
}
}
return idx;
}
Ready to run.
