Surprisingly, a topic of named function expressions doesn't seem to be covered well enough on the web. This is probably why there are so many misconceptions floating around. In this article, I'll try to summarize both - theoretical and practical aspects of these wonderful Javascript constructs; the good, bad and ugly parts of them.

In a nutshell, named function expressions are useful for one thing only - descriptive function names in debuggers and profilers. Well, there is also a possibility of using function names for recursion, but you will soon see that this is often impractical nowadays. If you don't care about debugging experience, you have nothing to worry about. Otherwise, read on to see some of the cross-browser glitches you would have to deal with and tips on how work around them.

I'll start with a general explanation of what function expressions are how modern debuggers handle them. Feel free to skip to a final solution, which explains how to use these constructs safely.
