是否对JavaScript引擎尾部调用(TCO)进行了优化? [英] Are any JavaScript engines tail call (TCO) optimized?

问题描述

我有一个用JavaScript实现的尾部递归路径查找算法，想知道是否有(全部?)浏览器可能会出现堆栈溢出异常.

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.

推荐答案

ECMAScript 4规范最初是要添加对TCO的支持，但已被删除:

The ECMAScript 4 specification was originally going to add support for TCO, but it was dropped:

JavaScript中没有更多的尾部调用了吗?

据我所知，目前还没有广泛使用的JavaScript实现自动TCO.不过，这可能对您有用:

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

尾声优化

基本上，使用累加器模式可以达到相同的效果.

Essentially, using the accumulator pattern accomplish the same effect.
