Generate a random list or array using Javascript

Hey,

I'm trying to use Javascript to create a random list that consists of four numbers: 1,2,3 and 4. I javascript to create a random pattern i.e. 3,2,4,1 so that it will send the message to Matrixctrl to create a random drum pattern. I've looked online and found out that I can sort an array in a random order using this code:

var points = [1, 2, 3, 4,];
points.sort(function(a, b){return 0.5 - Math.random()});

However, I don't know how to incorporate this into Javascript for Max, because I have to make it so that Javascript sends out a random list from outlet 0.

How would I write the code in order for Max to read it properly? This is my best best so far:

inlets = 1;
outlets = 1;

setinletassist(0, "bang");
// so that Javascript knows when to start using a bang object in Max
var points = [1, 2, 3, 4,];
// The start of my array, which I want Javascript to spew out randomly

function myFunction() {
points.sort(function(a, b){return 0.5 - Math.random()});
document.getElementById("demo").innerHTML = points;
}
function bang(){
outlet(0, myFunction)
}

Thanks in advance!
