This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Array.include? (from ruby core) --- array.include?(obj) -> true or false --- Returns `true` if for some index `i` in `self`, `obj == self[i]`; otherwise `false`: [0, 1, 2].include?(2) # => true [0, 1, 2].include?(3) # => false
