Why do I have to create a title variable (wouldn't @title be sufficient?)
Hi there, I'm hoping someone can help explain something to me please.
In the attached code, as part of the initialize method, I think I'm creating a variable called @title which then contains the argument title when it has been passed in.
Why do I then have to create another variable called title which contains the variable @title? Could I not just call @title whenever I need it?
Many thanks in advance (these concepts are tough to get your head around!)
class Name def initialize(title) @title = title end def title @title end def first_name "Metal" end def last_name "Robot" end end name = Name.new("Clair")

def title creates a METHOD that returns the value of a variable, does not create a VARIABLE. Just like you have first_name and last_name methods. This allows you to query for specific attributes of the object, including the title. After creating a new object of this class using
thing = Name.new("Clair") you can do this:
How else would you access the @title this way if you don't have the title method?
