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 i, values = [],

for (i = 0; i < 10; i++) {

}
function add(val) {
sum += val;
}
function rsum(previousSum, currentItem) {
return previousSum + currentItem;
}
Ready to run.
