一般来说，函数式编程以更清晰和简洁而自豪。您没有副作用/状态管理的事实使开发人员更容易推理他们的代码并确保行为。这个真理能达到多远？

我仍在学习 Elixir，但给出了 Coding Gnome 的代码：

def make_move(game = %{ game_state: state }, _guess)
  when state in [:won, :lost] do
    ...
end

def make_move(game = %{ game_state: state }, _guess)
  when state in [:pending] do
    ...
end

  ...
end

人们可以在 Javascript 中毫不费力地将其编写为：

def make_move(game = %{ game_state: state }, _guess)
  when state in [:won, :lost] do
    ...
end

def make_move(game = %{ game_state: state }, _guess)
  when state in [:pending] do
