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
In this test we look at some techniques for using Array
.
<script>
// Initialize
var result, array = 'A B C D E F G H I J K L M N O P Q R S T U V W X Y Z'.split(' ');
// "result" is used to prevent memory leaks found on tests.
</script>
Ready to run.
