Why does def id not have to define parameters in the def statement (like def initialize)? When is it appropriate to do so?

[mtf]

In Ruby, return is implicit, which means variables can be given a method wrapper and be returned as though they were directly referred. The parameter is only needed if the method needs it, otherwise, none.

Thanks - does that mean I can not directly refer to a parameter in the method that are not listed in the ()?

@data9124250570

I can not directly refer to a parameter

If there is no parameter then there is no local variable in the method. Am I reading your question correctly?
