Html helpers vs JSON

In Elm you build your views (if you're rendering plain HTML) using some helpers that you have to import. In Act you don't have to import anything, sice you just return JSON.

Elm

import Html exposing (Html, button, div, h1, text)

view : Model -> Html Msg
view model =
  div []
    [ h1 [] [ text (toString model) ]
    , button [ onClick Increment ] [ text "+" ]
    ]

Act

const view = (model) =>
  ['div', [
    ['h1', model],
    ['button', {click: 'increment'} , '+']
  ]]
