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.
var arr = [],
obj_arr = [],
obj = {},
obj_obj = {},
i,
times = 1000;
for(i = 0; i < times; i+=1) {
arr.push(i);
obj[i] = i;
obj_arr[i] = {v: 1};
obj_obj[i] = {v: 1};
}
Ready to run.
