Get rid of the :ok in a tuple of a function successful return

I’m not sure if the solution of @LostKobrakai is correct. What happens if one of smoothie would have :error instead of :ok?

Therefore I would use following result library which can handle this error state and the code could look like:

def get_smoothies_recipe() do
  smoothies =
    get_smoothies_url()
    |> get_smoothies_html_body()
    |> Enum.map(fn body ->
      [get_smoothie_name(body), get_smoothie_ingredients(body), get_smoothie_directions(body)]
      |> Result.fold()
      |> Result.map(fn [name, ingredients, directions] -> %{name: name, ingredients: ingredients, directions: directions}
      end)
    end)
    |> Result.fold()
end
