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
Measuring performance of removing the fraction off a float using four different methods, Math.floor(), parseInt(), a left shift (<<) and a binary OR (|)
i = Math.random() * 10000;
delete i;
Ready to run.
