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
Dramatically simplified for strings only and only two test cases; trying to get rid of variables and simulate Only the bare difference between the for and for in method.
var arr = ["foo", "bar", "baz", "derp", "herp", "foo"];
Ready to run.
