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
A quick check to see how variable assignment via ternary compares to a traditional if statement.
<p id="test">H</p>
<script>
var x;
var tl = document.getElementById('test').length;
</script>
Ready to run.
