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.

Out of bounds memory access in V8 in Google Chrome prior to 120.0.6099.224
You'd be surprised how much friction you'd have for C++ reflection. First, since it's a custom build step, you can do a mix of custom code gen and C++ constexpr/consteval for static reflection. Here's a header-only implementation for adding compile time reflection purely within the language [1]. And v8 already does dynamic code gen as part of its build process (to generate the snapshot to speedup instantiation of the isolate). Dynamic reflection is a must since JS is a dynamic language with reflection support.
Now of course, I don't know the specific details of reflection needed for the abstractions you reference and clearly V8 is still doing some amount of manual IR generation, so it's possible it would be a substantial investment to actually retrofit those techniques into v8. One would have to do a careful analysis of historical security exploits & specific techniques and their ability to prevent to figure out if it's worth adding those abstractions (especially since there is a potential performance tradeoff as you mention). As I said, I think there's insufficient research in this area to establish a compelling body of best practices (not to take away from the contributions of the GraalJS team to this space).

C++ Reflection for Component Serialization and Inspection
I’ve been using https://github.com/veselink1/refl-cpp for my recent project where i needed reflections, especially for serialization. Cant wait for c++48 and reflections in standard

Learn Modern C++
I have not done a "desktop" program in 25+ years and never using C++ (or C), since then I'm mostly a web developer (PHP,Elixir, JS, Kotlin etc).
I'm currently doing a C++ audio plugin with the Juce framework.
This website has been a good resource, alongside https://www.learncpp.com
But I was actually close to give up before using those two things:
- https://github.com/nlohmann/json : my plugin use a json api backend and the Juce json implementation is atrocious (apparently because of being born in previous c++ version), but this library is GREAT.
- ChatGPT 4. I'm not sure I would have "succeeded" without it, at least not in a reasonable time frame. ChatGPT 3.5 is slow and does not give good results for my use case but 4 is impressive. And I use in a very dumb way, just posing question in the web UI. I probably could have it directly in MSVC?
Also I must say, for all its flaws, I have a renewed appreciation for doing UI on the web ;)

What C++ library do you wish existed but hasn’t been created yet?
https://github.com/nlohmann/json works well for me

It is either a clever technique or a sad failure
Here is one popular C++ library (nlohmann/json) removing its use.

How to compile project to separate files to prevent having single large executable as a result?
Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json
- What are some ways I can serialize objects?

Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.
