Discussion on: Do we really need classes in JavaScript after all?

Main benefit I get out of ES6 classes is defining the shape of data I am dealing with, so I can talk and think about it in precise terms. When I say "Customer", I know exactly what fields and properties that entails (and IDE will help me remember it too).

Member functions and inheritence are less useful for the reasons you stated in your article. Any kind of business code I prefer to keep in pure functions or service objects, that are given class based objects to manipulate. Code and data kept mostly separate.

Mixins or composition patterns like yours don't really do much for me, as they muddy the waters of what each thing is and what can be done with it.

I like your approach. Classes are definitely good at creating data structures. Business logic in JavaScript can be tricky in class syntax (how I tried to point it out in the article).

Mixins or composition patterns like yours don't really do much for me, as they muddy the waters of what each thing is and what can be done with it.

The ideas behind hybrids library might be more clear to you if you look at the project documentation (especially Core Concepts section). I didn't want to mix subjects in this article and make it too long. In next weeks you can expect posts about those concepts on dev.to :)
