It's the same deal as with hungarian notation. Terrible idea.
Your function name should already describe what this variable contains. There is no need to duplicate this information with underscores. Name it "on_save" or "save_cb" instead. Even "save" will do fine in small functions.
This code will be read by humans, not computers. So there is no need to invent a "notation" just for the sake of it. Computers don't need it, and humans should get this info from the name/context anyway.

--Guys, what do you think to prefix all callback functions with double underscores? (or any other pattern that makes more sense to identify a callback)For example:model.save(data, __save);function __save(err, return) {...}I'm node/_javascript_ newbie, but using a prefix for callback names is making a huge different to scan the code (including using find features).Are you guys using some name convention approach for callbacks? Or is this just a newbie problem?Best regards,Filipe Deschamps--
