Unlocking The Power Of Case Equality: Proc#===

by AimredDevs —

Range, Class and Regexp all implement their own version of ===, so why not Proc?

Comments

You can shortcut multiples_of_5 = Proc.new{|*parameters| parameters.map{|i| i.modulo(5).zero?}.all?} to multiples_of_5 = Proc.new{|*parameters| parameters.all? { |i| i.modulo(5).zero?}}

Better and IMO nicer. regards

Thanks for the shortcut. We’ve changed that line to your version.
