chrome调试器调用堆栈异步选项意味着什么？

Question

我在call stack标题上看到了这个选项，虽然我正在打开它，我不知道它是什么意思，并且通过勾选它的含义是什么。

Answer 1

It's useful for debugging asynchronous JavaScript. It let's you view the entire call stack and walk the stack trace for event listeners ( setInterval, setTimeout, XMLHttpRequest and others ). I've found it particularly useful for watching the value of my variables through each async call.
