Some additonal note: the [] is an Array constructor.  It's a special
syntax for creating a new Array instance and appending elements given.
This is similar to "", '' and // which are also syntactic sugar for
instance creation:

irb(main):001:0> String.new
=> ""
irb(main):002:0> ""
=> ""

Kind regards
