AST visitor / walker in JS

[ivands]

Will there be an official AST visitor/walker in JS?
SWC sadly doesn't have this.
I did find an AST walker third-party package for SWC but it has bugs.
It would be great if a fast Rust JS parser could provide this feature.

My use case is that I'm building a package that generates a cache-key/fingerprint of a JS file based on the code and it's dependency versions.

I haven't checked yet but https://github.com/Rich-Harris/estree-walker should work.
