Issue with "Uint8Array" (and other TypedArray concrete class pages): missing inheritance from %TypedArray%

What specific section or headline is this issue about?

No response

What information was incorrect, unhelpful, or incomplete?

These pages mention things like Uint8Array.prototype.copyWithin(). There's no such thing—only %TypedArray%.prototype.copyWithin(). There's no need to repeat these methods on every constructor's page—just include the inheritance from %TypedArray% in the left sidebar, like we do for Web API.

What did you expect to see?

Remove the redundant mentions of typed array methods on every concrete class's page—there's only one such method in JavaScript, not one per typed array class.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?

I'm pretty sure this has been brought up in the past but I can't find the thread anywhere now. Inheritance information in the JS references is incredibly unuseful—literally everything says "inherits from Function", but that's just the constructor, not the actual class. This data is also hardcoded in the KS macro. Is it possible for us to extract it to the content repo?

Appears related to https://github.com/mdn/content/discussions/18002, but you're arguing for the sake of correctness, yes?

[Josh-Cena]

Yes, the fact that Uint8Array.prototype.copyWithin() is mentioned at all. It should just be shown in the left sidebar as inheritance.

Got it!

Furthermore, note that even the instance properties are accessors, implementated on %TypeArray%.prototype, so everything besides the constants and constructors, are inherited.

The constants are each loaded on the individual <ConcreteTypedArray>.prototype.
