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

Right shift one mask is same as divide by 2 on integers. A right shift operation is much faster than a division op. Most static compilers do this optimization.

```
var x = 100;
var y = 100;
```
