Rendering a simple JSON array with RABL in Rails

I tried to figure out how to make RABL rendering a very simple array of JSON strings, for example: ["my,"array","of","strings"]

Controller will be

class StringsController < ApplicationController
    responds_to :json

    def index
        @string = ['my','array','of','strings']
        respond_with @strings
    end

end

And the RABL view should start with:

collection @strings, root_object: false

but I can’t understand how easy it is to output lines without the name node or inside an object ...

Obviously, there is a much simpler solution for actually servicing the JSON array, like the one I put below, but I am particularly interested in why this seems so complicated in RABL!

class StringsController < ApplicationController

    def index
        render json: ['my','array','of','strings']
    end

end

To answer this question, I think it works with this:

collection @string, object_root: false

node :value do |s|
  s 
end

Note. I added :valuewhich is a JSON record label.
