I like this style of programming, but isn't there cause for concern in having such a deep call stack in JS?

  Yes. V8 and other JS compilers optimize tail calls, but it's not guaranteed by the standard. (i think IE doesn't, for example)

    I'm not sure where you got this idea. V8 does not optimize tail calls. It's easy to see this in the Chrome console, I just entered this now: var a = function(x) { if (x == 0) return 'done'; return a(x-1); }; a(100000); RangeError: Maximum call stack size exceeded http://code.google.com/p/v8/issues/detail?id=457 http://code.google.com/p/v8/issues/detail?id=457

      Wait, seriously? I didn't know that. Thanks for the link! Guess it's time for me to stop relying on that behavior...

  You could probably put a trampoline around it.
