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
const pattern = /[?&]utm_/;
const needle = 'utm_';
const matching_url = 'http://foo.com/?bar=baz&utm_source=12';
const non_matching_url = 'http://foo.com/?bar=baz&atm_source=12';
Ready to run.
