Are any JavaScript engines tail call (TCO) optimized?

Question

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

Answer 1

Pretty much every browser you encounter will barf on "too much recursion". Here's an entry in the V8 bug tracker that will probably be interesting reading.

If it's simple self-recursion, it's probably worth the effort to use explicit iteration rather than hoping for tail-call elimination.
