Summary
============

- Name mangling can provide a private attribute that is difficult to access accidentally
- Using closure you can create a private variable
- Properties have getter, setter and delete functions which are called when you try to work with the attribute
- You can create a private property using the property object and closure
- The property object has additional methods which allow it to be used as a decorator
