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
The first line tells luacheck that the variables `init` and `handler` are globals, and the second line tells it to ignore lines that contain just whitespace (a quirk the text editor I use uses to manage indenting levels).

In defense of blocks for local scopes
The 'do' keyword introduces a new scope (and can be used anywhere to do so). I format it as the former to be more explicit about the CONF variable being defined by the following code block.

HTTP Status 418 – I'm a teapot
I added the 418 response code to my gopher server [1]. There was one web bot that constantly hit it and was clueless that it wasn't a web server. It finally got a clue.

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.
