In Ruby, can we not access the instance variables of a Class directly ? It appears that it needs a kind of a getter method to acces it.

3

there are multiple ways to access the instance variable:

Ruby’s default encapsulation of instance variable is stricter then i have seen it in other languages.

thank you very much! I asked the question too early, it has been taught in the next chapter :slight_smile:

5

why does the instance variable need to be referenced as a symbol when using attrbute accessorrs ?
Example
attr_reader :color

although i have used a bit of ruby over the years, its not a language i know a lot of.

What did you expect to use instead of symbol?

Symbol doesn’t sound too bad, faster then strings and they are unique.
