numberArray.sort(function(){..} - DallasNYC

[a_modified_dog]

this is where i first came across the "harlem shuffle" -

for a fuller explanation, try googling for years as i have done ( if you ever find one, let me know ) or try to make sense of trace outs -

arr1=[1,2,3,4,5,6];;
arr2 = [1,2,3,4,5,6,7,8,9];

function shuffle(){
nVal = Math.floor(Math.random()*3)-1;
return nVal;
};

chk = 0;

function tracer(){
++chk>arr2.length ? clearInterval(traceInt) : null;
num = Math.floor(Math.random()*3)-1;
arr1.sort(num); 
trace("num = "+num+" returns - "+arr1);
arr2.sort(shuffle);
trace("nVal = "+nVal+" returns - "+arr2); 
}

traceInt = setInterval(tracer,50);
