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.

Ravi is a dialect of Lua, with JIT and AOT compilers
it's based off MIR, does it have something to do with https://mlir.llvm.org/ ?
for typed lua, there is another effort https://github.com/teal-language/tl in addition to the mentioned typescript approach: https://github.com/andremm/typedlua

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
- Why Fennel?

Algebraic data types in Lua (Almost) post
I wonder why the author doesn't use Teal [0] - a typed dialect of lua.

What's the deal with Fennel in Neovim?
There is already https://github.com/teal-language/tl, which is typed Lua. I think fennel exists to serve a different niche-- personally I use it not for any type features; I just like the syntax better, and others may find certain features like the macro system useful.

Using other languages
There's also some languages made to compile straight to Lua: - MoonScript is the most popular Lua wrapper - it's built to be more Python-like, featuring indentation-based scopes, function calls without parentheses, lambda syntax, list comprehension, and much more. - Yuescript is a modern update to MoonScript that adds more features (I haven't used it myself, so I'm not entirely sure exactly how it differs from MS). - Teal is a version of Lua that adds static typing for better code standards.

Bog – small, strongly typed, embeddable language
Terra and Nelua are both very different in goals than Teal. Teal is literally gradual types integrated into Lua keeping as many of Lua's idioms as possible (to a fault[1]). Terra and Nelua are both very metaprogrammable systems programming languages. Nelua's goals are primarily to soften C's rough edges, comparable to something like Nim.
There's another one you missed in Pallene[2]. But again, it's goal was to optimize the stack sharing involved in using the C API. It also adds types though and maintains Lua idioms as much as possible.

LuaX: A Lua Dialect with JSX
It would have been nice if LuaX was written in Lua.

Nelua, AOT statically typed Lua
That was somewhat of an entertaining read.
> Terra is C if you replaced the preprocessor with Lua.
This is what is written on the tin.

This is a good writeup on all the Alt-Luas https://injuly.in/blog/gsoc/
- data types in function definition
- You can make Lua compiled/statically typed using Teal... It's like TypeScript, but for Lua!

Lua, a Misunderstood Language
Odd to suggest that if they're interested in Lua, that they should check out Moonscript which is a different language altogether (although it compiles to Lua). But if you insist, something a little more Lua-ish is Teal[1] (gradual types ala TypeScript) or Pallene[2] (companion typed subset of Lua meant to generate optimized C libraries for use with Lua).
