Question

Is it possible to do something like this?

var foo;
foo.bar = function { };
foo.variable1 = "Hello World";
foo.variable2 = 5;

… and somehow make it so that I can:

function example() {
    foo(); // <-- have this call foo.bar()
    foo.variable1 = "Goodbye World"; // <-- but still have this work 
    }

Yup. Functions are just objects, too.

var foo = function () { alert("Hi!") };
foo.variable1 = "Hello world";

console.log(foo.variable1);
foo();
