Can i get some examples of “call it” please?


def array_of_10
puts (1…10).to_a

Call to method…



[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I can never remember which range operator is inclusive and which is exclusive. Above the assumption is ... is inclusive.


Gets me every time. I had a hunch that ... is exclusive, and .. is inclusive. The output above should read,

[1, 2, 3, 4, 5, 6, 7, 8, 9]

To include the 10, use

puts (1..10).to_a

THANK YOU SOOO MUCH!!! You are a code savior!! I have tried both ways with “...” and “..”!


You’re welcome!

Another gotcha that made me go back and check…

def array_of_10

The above signature line has no parameter. That means we can call it without an argument list…


This Ruby stuff may be fine for children, but us grown-ups are always on the hook where those binary decisions have to be made. (LOL)

What’s really neat about this is we store objects in methods, rather than giving them variables.

def array_of_10

puts array_of_10
[1, 2, 3, 4, 5, 6, 7, 8, 9]

And getting into more fun stuff…

puts array_of_10.map {|x| x * 2}


[2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

The array_of_10 method is truly a reusable object in every regard. And nary an assignment.
