我使用Q.js库编写了一个小型JavaScript应用程序，该应用程序在Chrome中运行良好，但在Firefox中无法运行。我收到以下错误：Q.js不适用于Firefox

我不确定是否正确使用库。该文档特别说明Q.async()函数是实验性的。您有推荐使用异步承诺的另一个库吗？
的代码是在GitHub可以在这里进行测试：
只需点击河流与相应的分水岭应绘制。
编辑：这里是相关的CoffeeScript代码。

嗯，“*脚本以超时结束*”错误难以重现，并且不提示错误的来源。到目前为止，我只能告诉你，'Q.async（）'不应该在调用时使用，而应该在定义时使用;在出现的代码中应该用'yield * processTile（）'代替。你的'go_get_dir'函数看起来非常复杂，很难理解。 – Bergi
