Adding methods to prototype

prototypes.rb

# even better, imho

class << `Document`
  # this goes in the prototype, so it ends up being on `document` too
  def root
    `return self.documentElement`
  end
end

class << `document`
  # this goes in the object itself, so only available in `document`
  def self.to_s
    "document"
  end
end

# better way?

class Document
  native_constructor `Document`

  def root
    `return self.root;`
  end
end




# awkward..

Class.extend_native_prototype(`Document`) do
  include Opal::Core

  def root
    `return self.root;`
  end
end

Class.extend_native_object(`document`) do

  def to_s
    `return "document";`
  end
end
