Here's a screenshot from someone's tutorial, where he is copy-pasting a snippet of code for starting an Express server in Node. Note how he feels the obligation to create a class (why?), and how its method names are capitalized (oh god why?). This must be a C# developer carrying his mindset over to a Node project.
I've probably written here that I don't understand classes, at least not to the point they get used for everything in some languages or frameworks. I sort of understand that they can be handy for co-locating data with functions, and I sort of understand that they can be a convenient instrument for code reuse; but some languages or frameworks insist on them religiously, even in places where neither encapsulation nor code reuse via inheritance is taking place.
