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.

A list of JavaScript engines, runtimes, interpreters

Can you make your own JavaScript by implementing ECMAScript standard?
Indeed. ECMA-262 has been implemented using JavaScript https://github.com/engine262/engine262.
-
What sorts of things would you consider to be “advanced” javascript concepts?
Node.js is not the only JavaScript runtime. JavaScript runtimes have been written using JavaScript alone, see engine262. There is also Deno, QuickJS, txiki.js, Bun, none of which use COmmonJS by default, SpiderMonkey, et al.

Ask HN: What interesting problems are you working on? ( 2022 Edition)
for an interpreted language like JS, this project is really nice https://github.com/engine262/engine262. More or less 2 parts: parser and evaluator
-
Is there a source that shows how built in js methods/functions are built?
That is a bit complex, so here's a list of JS engines: if you pick one written *in* JS, that would probably be most useful -- engine262 for example

then you might be impressed by https://github.com/engine262/engine262 as well

And so was the C compiler.

[AskJS] is there a way to quantitatively check if a number value is copied or only the pointer to that number is copied?
It's outside of what you asked for, but here's a JavaScript engine in JavaScript. Might make for some interesting bedtime reading!

Enumerating and analyzing 40 non-V8 JavaScript implementations
Interesting to see a JS implementation written in JS:

Jint
- Jint – A JavaScript Interpreter for .NET

Is there a way to dynamically interpret a string as javascript within a C# winforms program?
Jint https://github.com/sebastienros/jint
- Any framework/library for validating arbitrary code?
-
Scripting inside Rimworld with Unity: Impossible? With java it is a 3 liner.
There are quite a lot of ways to run scripting languages in C#. I've no idea what JSR223 is but .NET has DLR for example. There are also multiple libraries: IronPython, NLua, Jint and Jurassic for Javascript. There's also older version of CS-Script working with .NET Framework.
-
Is there any way to use Javascript to code in Unity anymore?
You can. Embeding lua is a trivial task, and I'm reasonably sure there even are plug-and-play solutions for that, and for JS there's JINT.
-
Running custom code from users
I personally use Jint (a multi-platform Javascript interpreter) since Roslyn is not available on mobile. It basically has the same kind of functionality as Roslyn, but it's JS. JS is well-known and accessible to everybody, but Roslyn might be faster since there's no double indirection when interpreting the script. It also depends on what language your users are comfortable with or could learn easily.

Classic BBS (code in comments)
Ah yeah, I looked into it more and decompiled the game to find that it appears they're using Jint to interpret the Javascript, and from testing with someone's REPL BBS server I can find that it's a pretty well isolated environment. Only ways around it I can think of are by exploiting some vulnerability in the sandbox to do external requests, modding the game itself to update the api, or running a parallel server to do some janky communication through the save state data.

.NET-compatible scripting languages for users to write their own scripts to query/manipulate objects/properties in the app
We used https://github.com/sebastienros/jint for scripting, it's ES5 JS implementation.

The experience of creating my own JavaScript runtime - #2
Jint is a JS interpreter with an integrated engine built in C#, like V8, he is responsible for all the base code execution as well as EcmaScript implementations such as default constructors, syntax, Promises... I studied its features in depth to start and it was a bit hard (in the beginning).
-
The experience of creating my own JavaScript runtime - #1
MelonRuntime is based on Jint, a JavaScript interpreter created by Sébastien Ros, software developer in the ASP.NET team at Microsoft. Melon works from bindings and functionalities injected into this interpreter together with external typing (provided by another package that comes with the default project generated by the command npx melon new) and built-in tools.
