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.

This year in Servo: over 1000 pull requests and beyond
I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

Roll your own JavaScript runtime, pt. 3
Not to forget the engine Charka: https://github.com/chakra-core/ChakraCore
The only bit of the old Edge that had its source emancipated. It was/is? quite performant.

Have you deployed Microsoft Todo to end users? How did you deploy it?
As a Linux user, I very much think Microsoft should have continued Trident and Chakra. Apple also should have continued releasing Safari for Windows. Our web QA setup was entirely built around Macs back then, but it was great to be able to test sites with Safari on Windows, and to have another responsive browser on Win32.

The Javascript Engine
Edge was initially using Chakra but has been rebuilt using Chromium and the V8 engine.

Crystal's Interpreter (2021)
https://github.com/chakra-core/ChakraCore/wiki/Architecture-...
I've found the source code to be quite readable too - albeit from a bug-finding perspective, not a strictly pedagogical one.
-
Exploring React Native’s new architecture
Furthermore, the new architecture decouples the JavaScript interface from the engine, enabling the use of other JavaScript engines such as Hermes, V8, or Chakra.

Enumerating and analyzing 40 non-V8 JavaScript implementations
I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: https://github.com/chakra-core/ChakraCore. But it looks like it’s still chugging along as a community effort rather than being completely abandoned.

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

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!
