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
jQuery $.inArray() vs handmade in_array() vs native indexOf()
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
function in_array(needle, haystack) {
var i = 0, n = haystack.length;
for (;i < n;++i)
if (haystack[i] === needle)
return true;
return false;
}
var arr = [1, 2, 3, 4, 5, "test", "", undefined, null, {}, true];
Ready to run.
