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
Does the length of an array matter if we're only accessing the first couple elements?
<script>
var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var array_large = [];
for (var i = 0; i < 1e6; i++)
array_large[i] = i;
</script>
Ready to run.
