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

function isEvenBit(n) { return 1&n === 0; }Ready to run.
| Test | Ops/sec | |
|---|---|---|
| Mod | | ready |
| Bit | | ready |
