an example of a module pattern, extending another object

extendedModule.js

var _ = require('underscore');

// an object that we will extend later
var foo = {
  baz: function() {
		// some interesting behaviour
	}
};

foo.baz.prototype.fubar = function() {
	// some interesting behaviour
};



// make our object (normally this would be in a different .js 
//                  file from the object being extended)
var be = {};

// add something to our object so we can prove it still has it
be.yuck = function() {
  // insteresting behaviour
};
be.something = 'interesting value';

// where the magic begins
// first we'll build the thing that is going to be added
// into our object, but then before we add it to our
// object we'll first extend our first object into this
// one.
(function(be) {
  var fubar = (function() {
		function fubar() {
			// interesting behaviour
		}
		return fubar;
	})();
	be = _.extend(be, foo);
	be.fubar = fubar;
})(be || (be = {}));

// and now we can use it
be.fubar();
be.yuck(be.something);
be.baz();
