  • It's mostly a matter of what your preference is.  As you state, you will lose call stack information in any exceptions/error reports and while working in the debugger if you use anonymous functions for everything.  However, sometimes they also make a lot of sense.  The guideline I use my apps is basically if the unit of work being done by a particular function is useful enough in an error report/exception stack trace.  If the parent (the call right before the anonymous function) is enough to tell me what I need to know, I won't name it.  If it isn't enough (e.g. for success/progress/error handlers in promises) I will name it so I know exactly which one was called when looking at a call stack.
