What are the classes and proxies?
Class- You can use the patterns easily with OOP based class declaration. It works readily with constructors, supports base class access, inheritance and static methods. OOP refers to Object-Oriented Programming.
Proxies- With proxies, you get to create objects and you can host the objects with a huge behavior diversity. Proxies can help in profiling and logging as well.
