When self is called the class method will return it's self. When executing `puts "Human class method 'name' is #{Human.name}"` it will return the class Human in the output: `self is Human`.
This returned result of Human through the self is #{self} Human line call is called by the self.name method defined in the Human class. The returned result of self in `Human class method 'name' is heather haas` is outside of the method run so the return is the instance method – heather haas.
class Human
@@name = "heather haas"
def self.name
puts "self is #{self}"
return @@name
end
end
puts "Human class method 'name' is #{Human.name}"
self is Human
Human class method 'name' is heather haas
It’s good to know ones self
