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.

Elm Compiler Written in Elm
There was a similar project to `go fix` with elm-upgrade (https://github.com/avh4/elm-upgrade). We migrated a ~100k LOC app at work from 0.18 to 0.19 and while it was tedious, the compiler really has your back and makes it easier.
We weren't bit by the removal of native/kernel code, but it definitely turned a lot of people away that may have been committed to Elm before.

Union, intersection, difference, and more are coming to JavaScript Sets
relevant issue, which is at the crux of this problem: https://github.com/tc39/proposal-record-tuple/issues/387

The Everything NPM Package
There are still so many basic things that aren't in the JS stdlib, though. A good example is Map - if you need to use a tuple of two values as a key, you're SOL because there's no way to customize key comparisons. Hopefully we'll get https://tc39.es/proposal-record-tuple/ eventually, but meanwhile languages ranging from C++ to Java to Python have had some sensible way to do this for over 20 years now.

Deep Cloning Objects in JavaScript, the Modern Way
If you’re reaching for structuredClone, what you really want is native immutable Record and Tuple syntax, and the companion “deep path properties” syntax which allows for efficient and ergonomic immutable updates:

Cool language features that Rust is missing?
It will be called "record" in JavaScript which will swing the popularity back the other way I guess (currently a language proposal)
-
Why doesn't TypeScript properly type Object.keys?
I suspect considering the strong desire to maintain consistency with JavaScript, we will eventually see something that when the Record proposal passes through tc39

ES2023 features list!
I hope the Record and Tuple proposal makes it through

ES2023 introduces new array copying methods to JavaScript
I mean, I'd love some real immutable/persistent data structures in JS by default, or even some Immer-like syntax sugar. Something like the record/tuple proposal would be awesome.

What's new in ECMAScript 2023
This will become very useful once Records and Tuples are a thing, because it allows you to store object references in a record/tuple (which by definition can only contain primitives).

The huge potential of Kotlin/Wasm
Also, js has an ongoing immutable value data types proposal.
