Copying properties from one object to another

[apatterno]

I have an Object, and I need to copy all its properties to another Object. I have tried simply assigning one object to the other like this: myNewObject = myObject;

However, that causes a weird problem. When I change a property of myNewObject, the same property changes in myObject!

Please help, I don't understand why setting values in one object should affect values in another.
