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

```
var numbers = [];
//generate amount random numbers
for (var i = 0; i < 100000; i++) {
numbers[numbers.length] = Math.floor(Math.random() * 100000) / 10000;
}
```

Ready to run.
