The global Object’s assign method is the “old” way to inherit prototypes. ES6 syntax did not add new language features; they were there all along.

Thanks a lot for all clarifications.

No problem. A good exercise I used to do was writing inheritence patterns first with pre-ES6 syntax, then constructors, then classes. They are, of course, interchangeable but it’s not wise to rehearse an anti-pattern.

EDIT: I said assign method earlier, I meant create. The assign method is the pre-ES6 way of creating object instances. Object.create() is used to inherit prototypes. That’s such a common mix-up that I’m embarrassed I didn’t catch it.

I just don’t use ES6. It’s amazing. I have such a smaller language surface, and so much more predictable and debuggable code. Not a popular approach though.

(Of course I can and do use ES6 when coding for other people, I write to whatever standard is established in a codebase.)
