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
Check if faster to process is parseInt or double negation: ex. parseInt(10.5) or ~~(10.5)
Ready to run.
| Test | Ops/sec | |
|---|---|---|

| tilda positive | | ready |
| parseInt negative | | ready |
| tilda negative | | ready |
