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 History of Lua
> Also it is technical and not user-friendly for windows users, because luarocks (package manager) is unusable there unless you’re skilled in C build systems and are ready to fix these issues.
I've found using hererocks[1] makes setting up lua and luarocks on Windows very easy. Running it in visual studio's command prompt has let me install pure Lua and C rocks.
However, I've noticed many rocks aren't updated on luarocks and the best way to install them is to point luarocks to the rockspec file in their git repo. (Instead of `luarocks install testy` you do something like `luarocks install https://raw.githubusercontent.com/siffiejoe/lua-testy/master...` .)

The simplest instructions for installing the latest versions of lua + luajit + luarocks together on linux
You might like hererocks. I've found it to be the easiest way to get up and running with Lua on any system that already has Python.

[linux] Installing lua from source
Never used luaver but I can recommend hererocks. It's like pyenv but Lua. Just run ./hererocks.py --lua 5.3 --luarocks latest {location_to_install}.

Building a baseline JIT for Lua automatically
As far as I can tell, they aren't.
http://lua-users.org/wiki/SandBoxes
There is a lot of information there, but it doesn't handle resource exhaustion, execution time limits or give any guarantees. It does indicate that it's possible, and has a decent example of the most restrictive setup, which is a good start. But I would for example compare it with Luau's SECURITY.md.
From https://github.com/luau-lang/luau/blob/master/SECURITY.md:
> Luau provides a safe sandbox that scripts can not escape from, short of vulnerabilities in custom C functions exposed by the host. This includes the virtual machine and builtin libraries. Notably this currently does not include the work-in-progress native code generation facilities.
> Any source code can not result in memory safety errors or crashes during its compilation or execution. Violations of memory safety are considered vulnerabilities.
> Note that Luau does not provide termination guarantees - some code may exhaust CPU or RAM resources on the system during compilation or execution.
So, even luau will have trouble with untrusted code, but it specifies exactly what happens and so on. I think that's fair enough.

Alternatively, Luau is a well-supported Lua variant with type checking and performance improvements, aimed more towards being a sandboxed embedded scripting environment.

Lua Criticism Is Unwarranted
I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.
I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example
function foo(x: number): string

Ask HN: Looking for platforms, other than Roblox, that have adopted Luau
Looking at other replies here, I can see I wasn't the only one who didn't realize there is Lua and Luau. Luau is an extension of Lua: https://luau-lang.org/
> Luau is syntactically backwards-compatible with Lua 5.1 (code that is valid Lua 5.1 is also valid Luau); however, we have extended the language with a set of syntactical features that make the language more familiar and ergonomic.

Embeddable Common Lisp 23.9.9
Lua is usually the embedded language of choice. If you are focused on security, you could check out the Roblox fork, Luau (https://github.com/Roblox/luau) where the creators took extra care to lock down the language on what scripts could do.
