node.js是否支持yield? [英] Does node.js support yield?

问题描述

有什么方法可以将生成器放入node.js?

我目前正在用回调伪造它们，但是我必须记住检查生成器函数内部的回调响应，该函数会创建很多if (callback(arg) === false) return;

我想要类似python的内容:

for p in primes():
  if p > 100: break
  do_something(p)

我正在像这样的节点中做

primes(function(p) {
  if (p > 100) return false;
  do_something(p)
});

也许像咖啡脚本之类的东西可以帮助您?

解决方案

是的，自版本0.11起.享受吧！

Is there any way to get generators into node.js?

I'm currently faking them with callbacks, but I have to remember to check the response of the callback inside of my generator function which creates a lot of if (callback(arg) === false) return;

I want something like in python:

for p in primes():
  if p > 100: break
  do_something(p)

which I'm doing in node like this:

primes(function(p) {
  if (p > 100) return false;
  do_something(p)
});

Maybe something like coffeescript could help?

解决方案

Yes, since version 0.11. Enjoy!
