Javascript to Continuation Passing Style

Question

I am trying to get the hang of CPS and was wondering if anyone could walk me through converting this example function:

function recur(n) {
    if (n == 0) {
        return 1;
    } else {
        return n * recur(n-1);
    }
}

I know that the beginning goes

function recur(n,cc){
if(n==0){
cc(1);
} else{
....
}
}

but im not sure how to do the recursive call. any help would be super appreciated
