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 x = -3.999;
var y = 3.999;
var z = 125.11111;
var mathTrunc = function( val ) {
return val < 0 ? Math.ceil(val) : Math.floor(val);
};
```

Ready to run.
