The argument that stack traces are easier to debug when functions are named is always brought up when talking about the issue of naming functions. However, I don't quite understand why it's such a big issue. Whenever I get a stack trace the issue is almost always easy to debug. That has been my experience working with JavaScript full time for two and a half years.

And every difficult to debug bug hasn't been related to knowing which functions are in the stack, but are instead related to figuring out why frameworks do something or race conditions and so on.

I just find it surprising that people are having problems with anonymous functions in stack traces, when I've never seen that.
