best ruby cheat sheet

class DerivedClass < BaseClass; end # if you want to end a Ruby statement without going to a new line, you can just type a semicolon.

class DerivedClass < Base
  def some_method
    super(optional args) # When you call super from inside a method, that tells Ruby to look in the superclass of the current class and find a method with the same name as the one from which super is called. If it finds it, Ruby will use the superclass' version of the method.
      # Some stuff
    end
  end
end

# Any given Ruby class can have only one superclass. Use mixins if you want to incorporate data or behavior from several classes into a single class.
