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.

Be aware of Arrays - V8 engine advice
For debugging elements kinds to figure out a given object’s “elements kind”, get a debug build of v8 (either by building from source in debug mode or by grabbing a precompiled binary using jsvu), and run: out/x64.debug/d8 --allow-natives-syntax Note that “COW” stands for copy-on-write, which is yet another internal optimization. :))

Can you make your own JavaScript by implementing ECMAScript standard?
See jsvu.

How much JS is enough for reactjs/nodejs
There is more than one JavaScript engine besides V8 https://github.com/GoogleChromeLabs/jsvu. Frameworks are not necessary at all to master JavaScript as a whole.

When is it better to use NodeJs and when is it better to use C#? What advantages does one have over the other?
Node.js is not the only option for JavaScript engines. There are several, including Deno, QuickJS, et al. https://github.com/GoogleChromeLabs/jsvu.

Javascript readability vs performance: a false tradeoff
To get a better understanding of why our clever one-liner FizzBuzz solution is slower, we need to take a look at how V8 works. V8 is the Javascript engine that powers NodeJS, you can directly download a binary version of the engine either via JSVU instead of compiling locally.

Jsc: My New Best Friend
Tangentially related: jsvu seems to be the easiest way to install most JS engines on most platforms. This can be useful comparing performance or compatibility across JS runtimes without firing up emulators.

Can you make your own JavaScript by implementing ECMAScript standard?
Technically you can run Node.js in the browser right now now.
-
Can you use JavaScript to create an app that installs Node.Js then deploys the (or an) app?
Here is an example of downloading Node.js, extracting node executable, compiling to WASM to use node in the browser https://github.com/cemalgnlts/now.

What sorts of things would you consider to be “advanced” javascript concepts?
Just to demonstrate how finicky folks on this r/learnjavascript are: I shared this Node on Web. Use Nodejs freely in your browser with Linux infrastructure. here and on r/node. r/node folks get it, that is, the work that had to go in to making that a reality. Folks on this r/learnjavascript evidently don't get the effort it took to make that so, after StackBlitz announced "... run Node.js, entirely inside your browser" only to walk back from that claim here https://github.com/stackblitz/webcontainer-core/issues/658#issuecomment-1091004244 "We currently do not expose a way to use WebContainer outside of StackBlitz.com".

- This website lets you run linux in browser

IT department refuses to let me install Python and other programs/languages I need for my job.
For running programming languages other than JavaScript in the browser there is Emscripten and WebAssembly. There is v86, where a Linux build is compiled to WASM. Folks have written QuickJS into a Linux build compiled to WASM, Node.js into the Linux buildroot https://github.com/cemalgnlts/now, so Python or CPython can be written to the image and loaded into the browser as WASM as well https://github.com/pyodide/pyodide.
