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.

What would be the significant benefits if one would develop equivalent libraries that are available for Python for Lua/Nelua?
Lua is a small language and its "standard library" is very minimal. Lua's intended for embedding so usually the host program provides a broader standard library by exposing functions to lua. However, there are several standard library packages for lua: batteries and lume are focused on gamedev; Penlight aims at bringing the breadth of python's stdlib to lua; plenary.nvim for nvim plugins; and probably more for other domains. I'd definitely recommend checking these out to help get closer to functionality level of most other languages (I use both lume and batteries, but dropped penlight awhile back because I found some implementations confusing/overcomplicated/inconsistent).

The first release of DeathVim
Making a lua-based distro might benefit from packing in an existing lua utility library instead of starting your own: lume (useful single file of utilities) or batteries (organized into modules).

Thoughts on LUA?
Second, hot reload actually works and is usually instant. (lume has one you can adapt, I use gabe's class system and reload since it's already integrated). Since an instance of an object is a table, and functions on the object are elements in a table, you can swap out functions for their new values and keep your current state. By comparison, Unity's C# hot code reloading requires you to serialize your state because it needs to unload the AppDomain. It needs to rebuild the world with the new types. Most serialization occurs automatically, but often it doesn't and you need to add special callbacks to make it work. Regardless, for projects of any real size, it's slow. Not sure how Unreal's Live++ (Live Coding) works, but seems like you can't edit .h files.

Idiomatic way to differentiate an ordered table from an unordered one?
From lume:
-
JS-object-like functions for lua tables
Or check out Lume.
-
Lua Table Serializatio
Yeah, lume is not a tiny library, but you can simply take only the functions you need from it. It's source code is very easy to read and (de)serialization implemented there in pretty minimalistic way.

Spreading tables in Lua
I'm not very familiar with javascript and its spreading operator, but it seems to me that something similar is in lume. Check out lume.extend and lume.merge.

Free mods list
One option might be to look at the Path of Building “Data” folder. If you need them in another format (e.g. json), it wouldn’t be that hard to write a Lua script to export them in your preferred format (using this json library, for example.

A question about save/load.
If you don't want to reinvent the wheels, you might want a json encoder to transform data into strings and back. Or bitser if you want better performance and smaller files in exchange for human-readability.

Plain Text. With Lines
Honestly, I just went with JSON because there's a nice Lua library for it (thank you https://github.com/rxi/json.lua).
I haven't thought about the file format much so far, just the experience of writing in it as if it's the "ground truth". We all seldom open our text files in a hex editor.

Lua, Open lua file and display as a table
Get json.lua from here. Put it in your project directory alongside file1.lua.

Cant get highscore to save
Good point. How about this? It allows you to encode/decode Lua values into/from JSON.
-
Indexing / substrings
I like this json library and tend to use it for save files (also makes them easy to edit by hand while debugging). It gets angry if you use tables with a mix of string and numerical keys, but I'd advise against that anyway. I've also used binser, which is also effective and easy to use.

What are some alternatives?
DeathVim - A quick neovim setup.
haproxy-lua-http - Simple Lua HTTP helper && client for use with HAProxy.
lua-cjson - Lua CJSON is a fast JSON encoding/parsing module for Lua
haproxy-auth-request - auth-request allows you to add access control to your HTTP services based on a subrequest to a configured HAProxy backend.
Penlight - A set of pure Lua libraries focusing on input data handling (such as reading configuration files), functional programming (such as map, reduce, placeholder expressions,etc), and OS path management. Much of the functionality is inspired by the Python standard libraries.
