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.

What sorts of things would you consider to be “advanced” javascript concepts?
There are multiple JavaScript runtimes. SpiderMonkey is one example that has nothing to do with Node.js, see (js-compute-runtime)[https://github.com/fastly/js-compute-runtime].

JavaScript support hits 1.0 milestone on Compute@Edge
We listened to the community feedback, filled in feature gaps, and addressed many bugs in the SDK. Not only that, we’ve also overhauled the SDK reference docs making it easier for you to know what’s supported and how to implement the features. All the Fastly specific features of the JS SDK now have interactive example applications in the documentation.

Wasmtime 1.0
These are good questions! Here's some answers from the corner of the world I know best as a Wasmtime contributor at Fastly:
1. Spidermonkey.wasm is the basis of Fastly's JavaScript on Compute@Edge support. We have found it to be faster than QuickJS. The source code is here: https://github.com/fastly/js-compute-runtime.
2. Fastly Compute@Edge is built on wasmtime. You can develop web services for it in Rust, JS, and Go: https://developer.fastly.com/learning/compute/
3. Fastly's multi-tenant platform is closed source, but our single-tenant local development platform, which also uses wasmtime under the hood as well, is open source: https://github.com/fastly/viceroy. It isn't a big leap to make viceroy multi-tenant: Wasmtime provides everything you need, and all Viceroy would have to do is dispatch on e.g. HTTP host header to the correct tenant. Our multi-tenant platform is closed source because it is very specialized for use on Fastly's edge, not because the multi-tenant aspect is special.

Debunking Cloudflare’s recent performance tests
btw. for what it's worth their javascript to wasm is opensource:
- https://github.com/fastly/js-compute-runtime
- https://github.com/tschneidereit/spidermonkey-wasi-embedding
and besides that it is slower than nodejs it is still plenty fast (no matter that it is not as fast as they want) btw. it's startup is faster than node. (maybe better pgo might help)

Spinkube: Running WASM in Kubernetes
This reminds me of Lunatic [1], an Erlang-inspired runtime for WebAssembly. Unfortunately it seems like development stalled some months ago.

Spin 2.0 – open-source tool for building and running WASM apps
you can check out https://github.com/lunatic-solutions/lunatic for that

Flawless – Durable execution engine for Rust
Very cool, and the approach demonstrated might be of interest to a similar problem we have in Ambient (our WASM game runtime that has competing processes that may need to retry interactions.)
That being said - what’s the relation to Lunatic [0]? Are you still working on Lunatic? Is this a side project? Or is it something completely separate?

Async Rust Is A Bad Language
Curious too. I follow Lunatic [0] as a candidate for future use, and also wasmCloud [1].

Elixir and Rust is a good mix
There's a couple of Rust libs and frameworks inspired on Erlang in 'best of both worlds' attempts, such as https://lunatic.solutions
I found others like Lunatic before, but cannot remember right now.

Anything close beam/otp for other languages?
There is a really good initiative called Lunatic : https://lunatic.solutions/
