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
Additional comparison of className and getAttribute("class")
<div class="someClass" id="someElement"></div><script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
var el = document.getElementById('someElement');
function hasClass(el, selector) {
if ((" " + el.className + " ").replace(/[\n\t]/g, " ").indexOf(" " + selector + " ") > -1) {
return true;
}
return false;
}
function hasClass2(el, selector) {
if ((" " + el.className + " ").replace(/[\n\t]/g, " ").indexOf(" " + selector + " " ) > -1){
return true;
}
return false;
}
</script>
