function ConstructorFunction() {
this.someProp1 = "1";
this.someProp2 = "2";
}
ConstructorFunction.prototype.someMethod = function() { /* whatever */ };
function factoryFunction() {
var obj = {
someProp1 : "1",
someProp2 : "2",
someMethod: function() { /* whatever */ }
};
// other code to manipulate obj in some way here
return obj;
