extracting item from an array

This randomising function is like a coin toss, it gives a numerical result and displays it:

function Ran() {
var c = Math.random();
return (c < 0.5) ? [0, show0()] : 1, show1()];
}

I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.

What is the syntax for getting to the numbers? something like

var n = Ran().[0] ?

Hi,

function Ran()
{
var arReturn=new Array
(
1,
show1()
);

if(Math.random()< 0.5)
{
arReturn[0]--;
arReturn[1]=show0();
}

return arReturn;
}


alert(Ran()[0]);

----------------------------

var n = Ran().[0] --> Ran() must return a pointer of an object with property array
but Ran() is a pointer to code (return pointer of array).

You can simplify things by rounding the random number to return 0 or 1.

Code:

---

function flip() {
        return Math.round(Math.random())
}

---

alert(flip())

thanks to both

getting the hang of it...
