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.

Who did ever see before?
Proposal commit where they changed it from contains to includes for arrays in case anyone is curious: https://github.com/tc39/proposal-Array.prototype.includes/commit/4b6b9534582cb7991daea3980c26a34af0e76c6c

Rails is not written in Ruby
JavaScript supports monkey patching by modifying prototype objects too. But it is considered to be bad practice because it modify the behavior globally, and some method name conflict may cause trouble. An example is Array.prototype.contains couldn't be added because it will break another library, so it is renamed to Array.prototype.includes.

Hands up if you consider webpack as a horror sometimes
If extending global objects like that wasn't allowed then it wouldn't be a problem - that's the horrific part in my opinion. They even had to rename a new array method as it would've broken a popular library at the time.

Tree-shaking, the horticulturally misguided algorithm
I don't think that's a very good goal. Jettisoning the DOM means jettisoning accessibility and being able to leverage everything that the browser gives you out-of-the-box. You have to render to a canvas and build everything from scratch. I think Wasm is great for supplementing a JS app, not replacing it (e.g. using a Wasm module to do some calculations in a Worker). I like to use the right tool for the job, and trying to use something other than JS to build a web app just seems a little janky to me.
At one point, there was a Host Bindings proposal that would enable you to do DOM manipulation (it looks like it was archived and moved to the Component Model spec [1]). That would probably be the ideal way to avoid as much JS as possible. However, browser vendors have been heavily optimizing their JS runtimes, and in some cases, Wasm may actually be slower than JS.
I've been following Wasm's progress for several years, which has been slow, but steady. Ironically, I think the web is actually the worst place to use it. There's so much cool non-web stuff being done with it and I'm more interested to see where that goes.

3D and 2D: Testing out my cross-platform graphics engine
Well the great thing about WebAssembly is that you can port QT or anything else to be at a layer below -- thanks to WebAssembly Interface Types[0] and the Component Model specification that works underneath that.
To over-simplify, the Component Model manages language interop, and WIT constrains the boundaries with interfaces.
IMO the problem here is defining a 90% solution for most window, tab, button, etc management, then building embeddings in QT, Flutter/Skia, and other lower level engines. Getting a good cross-platform way of doing data passing, triggering re-renders, serializing window state is probably the meat of the interesting work.
On top of that, you really need great UX. This is normally where projects fall short -- why should I use this solution instead of something like Tauri[2] which is excellent or Electron?

Missing the Point of WebAssembly
While I don't necessarily agree with the unnecessary, unsupported casual, & cheap contempt culture here ("unshackle the web from the mess that is JavaScript", "places that don't really need these problems to be solved")...
WebAssembly component-model is being developed to allow referring to and passing complex objects between different modules and the outside world, by establishing WebAssembly Interface Types (WIT). It's basically a ABI layer for wasm. This is a pre-requisite for host-object bridging, bringing in things like DOM elements.
Long running effort, but it's hard work and there's just not that many hands available for this deep work. Some assorted links with more: https://github.com/WebAssembly/component-model https://www.fermyon.com/blog/webassembly-component-model https://thenewstack.io/can-webassembly-get-its-act-together-...
It's just hard work, it's happening. And I think the advantages Andy talks to here illuminate very real reasons why this tech can be useful broadly. The ability to have plugins to a system that can be safely sandboxed is a huge win. That it's in any language allows much wider ecosystem of interests to participate, versus everyone interested in extending your work also having to be a java or c++ or rust developer.

Steel – An embedded scheme interpreter in Rust
A. Sure, but it isn't sufficiently beneficial for the cost.
B. WebAssembly is immature for developing a plugin system because of the lack of a sufficient ABI: https://github.com/WebAssembly/component-model
C. There aren't any other languages that meet the criteria. Lua was a no-go from the start. The maintainers did not like the language, and it necessitated adding more C code to Helix which could complicate building even further. https://github.com/helix-editor/helix/discussions/3806#discu...

Bring garbage collected programming languages efficiently to WebAssembly
AFAIK GC is irrelevant for "direct DOM access", you would rather want to hop into the following rabbit hole:
- reference types: https://github.com/WebAssembly/reference-types/blob/master/p...
- interface types (inactive): https://github.com/WebAssembly/interface-types/blob/main/pro...
- component model: https://github.com/WebAssembly/component-model
If this looks like a mess, that's because it is. Compared to that, the current solution to go through a Javascript shim doesn't look too bad IMHO.

Rust Is Surging Ahead in WebAssembly (For Now)
The wasm idl (called WIT) is actively being worked on here: https://github.com/WebAssembly/component-model/blob/main/des...
Being able to access DOM is definitely an objective. It's just taking a lot longer than folks guessed to build a modular wasm ABI.
