CoffeeScript 中是否遗漏了 `do...while` 循环...?

问题描述

在 CoffeeScript 中，while 循环是标准的:

In CoffeeScript, the while loop comes standard:

while x()
   y()

但是，以下 不起作用:

However, the following doesn't work:

do
  y()
while x()

这只是第一个例子的糖:

And this is simply sugar for the first example:

y() while x()

CoffeeScript 是否带有至少执行一次的内置循环?

Does CoffeeScript come with a built-in loop that executes at least once?

顺便说一句，do 是关键字——它用于调用匿名函数.

As an aside, do is a keyword — it's used to call anonymous functions.

推荐答案

CoffeeScript 文档说:

The CoffeeScript documentation says:

CoffeeScript 提供的唯一低级循环是 while 循环.

我不知道至少执行一次的内置循环，所以我想替代方案是

I don't know of a built-in loop that executes at least once, so I guess the alternative is

loop
  y()
  break if x()
