Inheritance in JS is not widely used since even the concept of classes is still very new and technically not safe for use (not supported in IE), not because JS devs are somehow wiser and self-limiting themselves to one level inheritance.

(unless you mean prototype based inheritance which is very different beast)

All inheritance in JS is prototype based inheritance. The class syntax is just syntax sugar prototypes. In theory you can do all sorts of crazy things with prototypes. In practice people use them just like classes. The reason people don't use inheritance in JS has nothing to do with browser support.

And async/await is promise based yet it results in quite different programming style. It doesn't matter which primitives are used for feature implementation.

I don't think so. Since the advent of ES6/Babel/TypeScript I see inheritance on frontend daily.
