it was still an issue, the point is to teach current best practices

JS version update

There are no tests with functions as prototype. So solutions which just check that typeof proto === 'object' pass.

seems to work now.

are you sure ? I just passed it using Node v10.x

In the Information section, I think, there is some confusion between literals and primitives. A String literal like 'abc' is a primitive, and cannot be passed to Object.create(). But this is also true of any string variable, i.e. any variable whose typeof returns 'string': let str = String(); is also a string primitive and similarly cannot be used as a Prototype, despite the absence of a string literal in its definition.

To access inner [[Prototype]] property of object use its __proto__ property

In modern JavaScript, __proto__ is deprecated, and programmers are encouraged to use Object.set/getPrototypeOf() instead

This kata doesn't work with Node v10.x. Everything is either null or undefined.

Brilliant!

that's a good code
