class SampleList
  include VirtualDOM

  def initialize(elements = [])
    @elements = elements
  end

  def render
    ul class: 'simple-list' do
      @elements.each do |string|
        li do
          text string
        end

    end
  end
end

$document.ready do
  list = SampleList.new(%w(one two three)).render
  back = SampleList.new(%w(three two one)).render

  root_node = VirtualDOM.create(list)
  $document.body.inner_dom = root_node
