This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Array.delete_at (from ruby core) --- array.delete_at(index) -> deleted_object or nil --- Deletes an element from `self`, per the given Integer `index`. When `index` is non-negative, deletes the element at offset `index`: a = [:foo, 'bar', 2] a.delete_at(1) # => "bar" a # => [:foo, 2] If index is too large, returns `nil`. When `index` is negative, counts backward from the end of the array: a = [:foo, 'bar', 2] a.delete_at(-2) # => "bar" a # => [:foo, 2] If `index` is too small (far from zero), returns nil.
