Yes. You get to drop the javascript compile and the graphql and you speak purely in three languages:

  1. elixir: def handle_event("save_customer", params, socket)...
  2. html: <form :for={@form} phx-submit="save_customer">
  3. And sometimes rarely javascript: this.pushEvent("reorder_customer_priorities")

That's it. No compiler, no type annotations, no graphql layer.
