描述

https://github.com/tmpvar/jsdom

This would need to mark all its objects as intrinsic automatically from inside the Prepack realm.

Constructors also need to be able to track how they were constructed. It can't construct using new HTMLDivElement() but it could do document.createElement("div").

I think this can mostly be achieved by treating everything as abstract and simple but it would be even nicer to be able to track expected side-effects so that even more can be done.

研究方向
Review Prepack's intrinsic object model in the source code (e.g., src/intrinsics directory). Study the JSDOM library's DOM class hierarchy and how objects like HTMLDivElement are created. The issue suggests marking all JSDOM objects as intrinsic and tracking constructor usage (e.g., document.createElement). Explore how Prepack can abstract these objects and track side effects to enable more aggressive optimizations. Note that the repository is archived, so further development may not be active.
