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
For some reason current Chrome is deopting when using push, so we're seeing really bad tests (+/- 30% margins = bad test).
var arr = [];
var arrLen = 1000;
while (arrLen--) arr.push(1);
var newArr = Array(arr.length);
function addOne(val) {
return val + 1;
}
arr = arrLen = newArr = addOne = null;
Ready to run.
