任何Javascript引擎尾部调用优化？

问题描述

我有一个使用Javascript实现的尾递归寻路算法，并且想知道是否有任何（所有？）浏览器可能会遇到堆栈溢出异常。

解决方案

ECMAScript 4规范最初将增加对TCO的支持，但它被放弃了。

$ b

据我所知，目前没有广泛使用的JS实现自动TCO。不过，这可能对您有用：

I have a tail recursive pathfinding algorithm that I've implemented in Javascript and would like to know if any (all?) browsers would possibly get stack overflow exceptions.

解决方案

The ECMAScript 4 spec was originally going to add support for TCO, but it was dropped.

As far as I know, no widely-available implementations of JS currently do automatic TCO. This may be of use to you, though:

Essentially, using the accumulator pattern accomplish the same effect.
