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 mathAbs = Math.abs;
function bitAbs(x) {
return (x ^ (x >> 31)) - (x >> 31)
}
function bitAbs2(x) {
const mask = x >> 31;
return (x ^ mask) - mask;
}
```

Ready to run.
