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
If you have a known static object, you can cache the stringified version for later parseing. Is this enough to swing object copies in the favor of JSON.parse over $.extend(true,{},{})?
Stay tuned...
