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.

Hyperlight: Virtual machine-based security for functions at scale
I believe the team has a working build of JerryScript [1] to test out the C bindings, but I’m not sure that will be released.
My understanding is that work on the Wasmtime VM guest is ongoing, which will enable Hyperlight to run the SterlingMonkey engine [2]. This is a WebAssembly build of Firefox’s SpiderMonkey engine which was donated by Fastly to the Bytecode Alliance.
That said though; I agree it would be great to see runtimes like V8 and JSC run directly on Hyperlight. There are good reasons why people might prefer those over StarlingMonkey (compat comes to mind), and it would be neat to see how much faster they could start compared to conventional VM deployments.

DeviceScript: TypeScript for Tiny IoT Devices
I've been having a lot of fun with https://kalumajs.org/ recently for silly JS embedded things. It's been great so far, and has a cool little community!
It's a runtime built on top of JerryScript, which has been pretty neat to look into as well: https://jerryscript.net/

JavaScript embedded inside Elixir
I personally quite like JerryScript

Kaluma - tiny JavaScript runtime for microcontrollers - includes a browser-based IDE that can communicate with a Raspberry Pi Pico and other RP2040 boards via Web Serial API. Write code in the browser (in JavaScript), then copy and run it on the board with a click of a button.
Based on JerryScript, the creators also provide an IDE and serial communication tool on their website. There's also ample documentation and guides. Looking forward to getting more into this.

Bun v0.6.0 – Bun's new JavaScript bundler and minifier
i just tried recompiling v0.0.2 (https://github.com/just-js/just/releases/tag/0.0.2) of just-js and comparing it to current. for the completely static build on ubuntu 22.04 i see following:
0.0.2 (v8 v8.4.371.18) - file size: 15.2 MB, startup RSS: 8.4 MB

Is Scala to Java the same relationship as TypeScript has with ECMAScript?
Not at all. Javascript, as well as java compiled into the bytecode, but just incrementally and at the runtime. You cannot compile typescript into bytecode directly (at least it intend to be like that). You can even compile js to executable (https://github.com/just-js/just). So no, typescript transpiles to javascript, whereas scala compiles to bytecode, it's different things

A C++ web/application framework I have been building for the last 12yrs
Trust me, these guys are insane and go to really extreme levels and use optimization techniques which are not generally prevalent among the general programming fraternity. for eg, look at pico.v it is awesome and just-js is truly unbelievable, then there is faf, most of them combine low level programming trickery to reach those insane numbers. Also some of the code may not be useful in a production app but they actually extract the juice out of the metal at every instance. Memory optimizations, compiler optimizations, postgresql wire implmentations, rust black magic, these guys are really crazy and passionate.
