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
Tests to determine which function is faster for detecting whether a string matches a regex pattern.
<script>
var regex = /\/[\d\w]+\/arguments\/[\d\w]+\/reports\/[\d\w]+\/comments\/[\d\w]+\/vote$/;
var str = '/bushtaxcuts/arguments/5EfVm/reports/9oJHN/comments/09iK2/vote';
</script>
Ready to run.
