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
The snippets I’m comparing here aren’t quite the same, but for HTTP-only websites it doesn’t make a difference. See the “Use the protocol check only when it’s needed” section in my article on optimizing the asynchronous Google Analytics snippet for more information.
var location = window.location;
Ready to run.
