var string = "0,1"; var array = [string]; alert(array);
In this case,
alert would pop-up a
0,1. When it would be an array, it would pop-up a

For simple array members like that, you can use
var array = JSON.parse("[" + string + "]");
This gives you an Array of numbers.

Array.prototype.map, though you’d need to shim it for IE8 and lower or just write a traditional loop.
var array = string.split(",").map(Number);
