Why Does This Work?

var Me = {
                "name": "Andy";
        greet: function () {
            console.log("Hello, I'm " + this.name);
        }
};

var Richard = {
            "name": "Richard",
            greet: Me.greet //works because we're not dealing with things that are inside a function?
};

Me.greet();
Richard.greet();

Returns: "Hello, I'm Andy" and "Hello, I'm Richard"

I'm not sure how Me.greet is accessible from inside the Richard object? Is it simply because we're not dealing with things inside functions, therefore it's all in the same Scope?

Hey Andrew,

You're right. Both objects are in the same scope. Scope is defined only by functions, so your Me object is a global object, given that it isn't inside of a function. This means that any properties that belong to it, like greet in this case, are accessible from anywhere.

I have to say thought, Kevin, the last module, 'Prototypes 2', bent my mind. Completely lost me!
