Static variables in JavaScript

Question

How can I create static variables in Javascript?

Answer 1

If you want to declare static variables for creating constants in your application then I found following as most simplistic approach

ColorConstants = (function()
{
    var obj = {};
    obj.RED = 'red';
    obj.GREEN = 'green';
    obj.BLUE = 'blue';
    obj.ALL = [obj.RED, obj.GREEN, obj.BLUE];
    return obj;
})();

//Example usage.
var redColor = ColorConstants.RED;
