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.

hscpp: An experimental library to hot-reload C++
hscpp (Hotswap C++) is an experimental library I created which allows you to hot-reload C++. It was heavily inspired by Runtime Compiled C++, and works by linking DLLs into your project at runtime.

Continue with Javascript or switch to C++
The only recent attempt to make something like this practical, as far as I know, was RCCpp. Going by the GH activity, it looks like it kind of went nowhere.

I want to make my game a dll that can use functions from my engine exe
FYI I maintain a list of runtime compiled C++ approaches on this wiki: https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledCPlusPlus/wiki/Alternatives

Reloadr – Hot code reloading tool for Python
There is https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledC...
The idea is to use virtual functions, and recompile new classes into a shared library. The shared lib is linked into the running program, and old instances of the classes are deleted and replaced by new instances constructed from the share library.
I am working on a library using the same (stolen) idea here:
https://github.com/jheruty/hscpp
Proof of concept demo:

hscpp is still very alpha, and I’m sure I’ll find lots of bugs as I work on a “real” demo. In contrast, Runtime Compiled C++ is quite mature and is used in real game projects.
Note that this approach very much limits your architecture. For example, you won’t be able to use statics, as the newly compiled shared libraries won’t see them.
It’s a finicky thing, worth it to me, but not something you can just plop in to an established project.

Quine or self reproducing program written using C language
Well of course it's possible to generate executable code at runtime in C++ since clang itself is written in C++, but it's definitely a much larger undertaking, but there's two such efforts I know of, Cling and RuntimeCompiledCPlusPlus.

hscpp: An experimental library to hot-reload C++
I much prefer the approach taken by cr.h which monitors a "plugin" binary instead and acts as a simple wrapper around platform specific dll/dylib/so loading. You then have a multitude of strategies if you need persist state such as serialization, placing code or data on the host side and using virtual methods/fptrs, holding third party lib references to dlls on the host side or using the CR_STATE mechanism for simple things.

What are good Lua alternatives as an embeddable language?
Depends on your use case, but I would second the option of just hot reloading c++. I have been experimenting with that (using cr.h) and its great - as long as you make sure your compile and link times are fast enough.
