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
const isEven = x => !!(~x & 1)
const isEven2 = x => Boolean(~x & 1)
const restEven = x => !(x % 2 !== 0)
const n = Math.floor(Math.random() * 999)Ready to run.
| Test | Ops/sec | |
|---|---|---|
| Bitwise comparison (double negate operators) | | ready |
| Bitwise comparison (with boolean function) | | ready |
| classic isEven function (with suport to negative numbers) | | ready |
