Simplest way to generate an unquoted Javascript option (for example, for a function)

javascript_unquoted.rb

class JavascriptUnquoted
  def initialize(text)
    @text = text
  end
  
  def to_javascript
    @text
  end
  
end

class Hash
  def to_javascript
    script = self.inject([]) do |items, (k,v)|
      pair = [k.to_json]
      if v.respond_to?(:to_javascript)
        pair << v.to_javascript
      else
        pair << v.to_json
      end
      items << pair.join(':')
    end
    "{#{script.join(",")}}" 
  end
end
