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
Simple bench to try to determine whether RGBA or opacity/background-color are faster for simple leaf nodes in a DOM Tree.
<div id="testNode"></div>
<script>
var testNode = document.getElementById('testNode');
testNode.background = 'red';
</script>
Ready to run.
Test | Ops/sec | |
