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:

function nextInt(n){
return Math.floor(Math.random()*n);
}
function nextRGB(){

}
let a = nextInt(256*256)+2;
let b = nextInt(256*256)+2;
let x = nextInt(256);
function nextInt2(){
return x = (a * x + b) % 256;
}
function nextRGB2(){
return [

Ready to run.
