I hope that the very generic names you have chosen is just for the example, but otherwise that is exactly the type of names that make a codebase incomprehensible. How about something like function CalculateSalesBonus(err, salesmenEmployedByTheLastOfMonth) { // do stuff } which actually contains much more information than db.getSalesmenEmployedByTheLastOfMonth(function (err, data) { //blah blah does stuff });
