This project aims to classify the use of JavaScript (JS) on the web into common functionalities called spheres. Our methods are documented in various markdown files on the top level this repository, data are posted in Issues and Releases, the preliminary results are in the report, and we have a poster.
In a nutshell, we crawl top websites and collect logs of
API calls per JS script using VisibleV8, then apply heuristics to
classify each script into spheres.
The main problem is that many scripts are large and fall into multiple spheres,
so we rewrite them into scripts containing smaller blocks of eval calls
(the eval trick).
We have decided to pause this project due to its limited value and various problems, but if you are interested, feel free to reach out to @SichangHe.
