I'd personally use `programWithArgs`, or just `program` and bake flags in,
defaulting to an empty tuple or some other nil type or so that comes from
javascript's `undefined`. Like define init via `init () = { blah model }`
for the 'no argument' case, that way it accepts 'undefined' from
javascript, such as when there is no argument passed in from javascript.
