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

Zepto vs. Jquery vs. raw JS for getting an element by id
<script src="//cdnjs.cloudflare.com/ajax/libs/zepto/1.0rc1/zepto.min.js">
</script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="asdf">
</div>
function el(string) {
if (string.indexOf('#') === 0) {
return document.getElementById(string.substr(1, string.length));
}
}
//to be fair, I'll wrap getElementById in a function and return the object
function byId(id) {
return document.getElementById(id);
}
var boolean = true;
Ready to run.
