I could not disagree more.

To me the readability benefit of classes, "extends" and "static" that work intuitively, "constructor", "super", etc. is immense, especially when you pair with something like Facebook Flow that let you declare the members with types. I consider it one of ES6's most compelling features. No more writing out "MyClass.prototype" just to declare basic classes with methods.

Absolutely -- having a typed object structure helps with tooling, as I mentioned. There are a lot of nice features that can be built around a solid type system to increase expressivity and improve safety. JS classes, as implemented, are an uninspiring facsimile of OO APIs, adding a lot of new syntax while papering over just enough semantic differences that it feels like a bit like an admission of defeat for the old paradigm.

I don't write nearly enough JS to say there is unequivocally a better way to write programs, but it's a bit disappointing that no one has figured out more advantageous ways to leverage the nature of the language without, IMO, leaning so much into cultural "learned behavior" from other OO languages.
