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
Is it faster to call hasOwnProperty directly or via call? How much faster?
<script>
var hash = {
a: 1,
b: 2,
c: 3,
d: 4,
e: 5,
f: 6
};
var keys = [ "a", "b", "c", "d", "e", "f" ];
</script>
Ready to run.
