Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Effective Code Browsing
Nice!
Have been working on something similar, although my use case is more about learning how code has changed across git commits: https://github.com/bugout-dev/locust
For Javascript/Typescript/React support, like you, I hooked into the Babel toolchain. Can't recommend it highly enough.
There's also a newish project called quick-lint-js which seems to have written their own from-scratch AST parser for JS, but I haven't tried it yet: https://github.com/quick-lint/quick-lint-js
Finally, another project that I know in this space is comby (I believe it is owned/maintained by the folks at Sourcegraph): https://comby.dev/
Don't know why I dumped all those links there. Just figured there may be something useful in them for you. Am also just super passionate about building knowledge about code bases by analyzing their ASTs. Nice to meet a fellow enthusiast. :)

What if Git worked with Programming Languages?
I maintain a free/open source project that does exactly what the author asks for: https://github.com/bugout-dev/locust.
Our tool uses git as the foundation of its functionality. It superimposes git diffs on top of ASTs.
It is insanely powerful.
For example, we use it to power semantic code search and current support Python, Javascript, and Java. We generate a JSON object defining the AST differences between initial and terminal commits on GitHub PRs and doing text search on the JSON objects performs surprisingly well when we want to answer questions like, "When did we add dateutils as a dependency?" or "When did we last change the /journals handler on the API?"
The Python integration currently sees the most use but if you are interested in other languages, we would be happy to support it.
Do drop me a DM if you want help getting started with Locust.

Diffsitter: A tree-sitter based AST difftool to get meaningful semantic diffs
My team has a similar project (Locust: https://github.com/bugout-dev/locust) where the goal is to learn the semantic meanings of code changes in git commits, GitHub PRs, etc.
Since we took git diffs as a target for semantic analysis, we have a different approach to our diffs. We start with line-by-line diffs (specifically using "git diff") and then take a semantic diff by superimposing the git diff information on top of the initial and terminal ASTs.
This makes the diff calculation cheaper because we don't have to do full diff between trees.
Haven't updated the code in a few months, but my team is actively using Locust on public GitHub repos to learn the semantics of those code bases. We do plan to do some work on it soon to make it easier to make Locust easier to use (especially as a library).
Really need to sit down and take a proper look at tree-sitter. We currently support Locust diffs for Python, Javascript, and Java, but each one is custom written and implements the same basic algorithm. It looks like tree sitter might just crush this problem for us.

Jpegli: A New JPEG Coding Library
JPEGLI = A small JPEG
The suffix -li is used in Swiss German dialects. It forms a diminutive of the root word, by adding -li to the end of the root word to convey the smallness of the object and to convey a sense of intimacy or endearment.
This obviously comes out of Google Zürich.
Other notable Google projects using Swiss German:
https://github.com/google/gipfeli high-speed compression
Gipfeli = Croissant
https://github.com/google/guetzli perceptual JPEG encoder
Guetzli = Cookie
https://github.com/weggli-rs/weggli semantic search tool
Weggli = Bread roll
https://github.com/google/brotli lossless compression
Brötli = Small bread

Meet ast-grep: a Rust-based tool for code searching, linting, rewriting using AST
I use weggli quite frequently for security analysis. Are there any plans for friendly competition in terms of equivalent features (not:, subexpressions, etc.).
