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

var arr = [],
i,
obj = {};
obj.length = 0;
for (i = 0; i < 10000; i += 1) {
var o = {
payload: i
};
arr.push(o);
obj[i] = o;
obj.length += 1;
}
Ready to run.
