Fooling around with closures. Defined a function that accepts an argument and returns a function that manipulates said argument. I believe my gist is just an example of object referencing.

gistfile1.js

function what(obj) {

	return function(str) {
		if (str) {
			console.log('name WAS: ', obj.name)
			obj.name = str;	
		}

		console.log('name is:  ', obj.name)
	}
}

function scope() {
	var obj = {name: 'yo baby'}

	return {
		myName:   what(obj),
		yourName: what(obj)
	}
}

var obj = scope();
obj.myName('hot stuff')
// -> name WAS:  yo baby
// -> name is:   hot stuff
obj.yourName()
// -> name is:   hot stuff
