I have this problem often with array methods, so i quess theres something im missing out.
I tried finding solution, but failed.
If you have any clue why it says that array is not a function (I am using it on an array), please tell. Also, a,b,c are defined in html.

```js
function jes(a, b, c) {
    a = parseInt(a);
    b = parseInt(b);
    c = parseInt(c);
    var arej = [a, b, c];
    var si = arej.pop();
    arej = arej.unshift(si);
    var ki = arej.pop();
    arej = arej.unshift(ki);
    var bi = arej.pop();
    arej = arej.unshift(bi);
    alert(arej);
}

```
