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
Comparing the performance of using style against changing directly cssText. Also compared against with just adding a css classname.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="element">
</div>
<style type=”text/css”>
.newClass { left: 10px; top:50px; }
</style>
Ready to run.
