This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Integer.times (from ruby core) --- times {|i| ... } -> self times -> enumerator --- Calls the given block `self` times with each integer in `(0..self-1)`: a = [] 5.times {|i| a.push(i) } # => 5 a # => [0, 1, 2, 3, 4] With no block given, returns an Enumerator.
