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.

Lua: The Little Language That Could
There's Lua implementation [1] in pure Rust, by the way.

Do Rust and Lua work well together?
The rust ecosystem is doubling down on wasm with little to no focus on lua (some would even prefer to build their own programming language) that doesn’t mean lua is pretty bad for the rust ecosystem it’s just that there’s no much focus as to compared to wasm Example I noticed is https://github.com/kyren/luster

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.

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).

[AskJS] Is JavaScript missing some built-in methods?
Record and tuple is at stage 2

The huge potential of Kotlin/Wasm
Also, js has an ongoing immutable value data types proposal.
What are some alternatives?
lua-cmake - Embed lua with CMake
zod - TypeScript-first schema validation with static type inference
passerine - A small extensible programming language designed for concise expression with little code.
Immer - Create the next immutable state by mutating the current one
lua-lockbox - A collection of cryptographic primitives written in pure Lua
typescript-eslint - :sparkles: Monorepo for all the tooling which enables ESLint to support TypeScript
moonsharp - An interpreter for the Lua language, written entirely in C# for the .NET, Mono, Xamarin and Unity3D platforms, including handy remote debugger facilities.
typescript-is
luau - A fast, small, safe, gradually typed embeddable scripting language derived from Lua
TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.
