cool. you could also write this input.map(&:capitalize) or input.map {|s| s.capitalize}.

be sure to take a look at the Symbol#to_proc method. it's very common.
https://ruby-doc.org/core-1.9.3/Symbol.html#method-i-to_proc

i.capitalize
end
end

cool. you can also use .grep which takes a regex pattern. it's super handy.
