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.

The absurd complexity of server-side rendering
It's still a long way from being complete, but I'm working on something like that[0]. Eventual plans are to have good Rust library interop (e.g. bindings to hyper for http) while also being able to compile to Wasm (to run on an erlang-style distributed runtime / the browser). The language is currently interpreted, but one I get typechecking working, I should be able to merge in the Wasm codegen backend I'm working on (with eventual plans for LLVM). Current compiler has zero external dependencies.
Language itself could be described as a mix of OCaml, Scheme, and Lua. Currently working on the hygienic procedural macro system and system injection through algebraic effects.

I wrote a Cozy Programming language
Passerine was the next language i decided to try to fit onto paka, but alas this one too was eventually put aside for the time being.

Scripting Languages of the Future
Tossing my hat in for Passerine [1]. Gorgeous ML inspired syntax. Built for scripting Rust applications.
Dreaming here: Lua is a fantastic scripting language, but the Rust FFI isn’t as ergonomic as it could be. Enter Luster [2], which is basically LuaJIT rewritten in Rust.
Embedding a scripting language in a Rust application gives you tons of power (e.g. scripting Rust structs from Lua [3]), and setting this up isn’t terribly difficult.

Extensible syntax?
Seed7 and https://github.com/vrtbl/passerine (and seemingly more as others have suggested) have direct / first-class support of syntax declaration/definition in a homoiconic way, as powerful as LISPs, but feels more "natural" compared to a LISP.
-
Achieving nullable ergonomics with a real optional type without special compiler privileges.
It used to work pretty well only if the core PL makes semicolons programmable, but given the development of effect systems, plus customizable syntax as in https://github.com/ThomasMertes/seed7 and https://github.com/vrtbl/passerine , I'd say, there are much more we can do about it.

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.
