To be fair, most of these complaints about functions in JS are because its roots are still a nice prototype-based programming language and the `class` syntax sugar implies class-oriented things that JS doesn't deliver and confuses prototype-oriented features as class-oriented bugs. You can still use them as features, though we are getting close to the point where using them as features is an art form for arcane wizards that will make many, many JS users scream in terror and confusion.
