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
Compare the speed of getElementById to querySelector
<p id="foo">Foo</p>
<p id="bar">Bar</p>
<p id="baz">Baz</p>
<script src="https://cdnjs.cloudflare.com/ajax/libs/zepto/1.0/zepto.min.js"></script>
var $$ = function(e,f,g){
return document[(e)?"getElementById":(f)?"getElementsByClassName":"getElementsByTagName"]((e)?e:(f)?f:g);
}
console.log(bar);
Ready to run.
