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
What's the difference in performance between:
$("input:checked");
and
$("input").filter(":checked");
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
for (var i = 0; i < 500; i++) {
document.write("<input type='checkbox' checked='checked' />");
document.write("<input type='checkbox' />");
}
</script>
Ready to run.
