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/

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.

📜 I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

I made JSON.parse() 2x faster
Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.
