#What is self?


Self can be confusing because it refers to something different depending on the context. 

It refers to the object on which it is called (this could be a class or an instance of a class).

In a class, it refers to the class itself, so if a class is called "Person", self is referring to "Person".

In the context of a class, if you call a def (a new method) inside the class without an explicit receiver, it will create a new instance method.
