Yeah! Long live Lua! :-)

Honestly, it's just a fancy way of saying I learned a few things from earlier attempts and made some tweaks. I just think "evolved" sounds cool!

Not yet, but I wrote this library to use in a project of mine. When I finish it, I will add a link to the README. As for a small demo project, I have one in mind, but I haven't started it yet.

Yeah, tiny-ecs is good, but it doesn't quite fit my needs. With these thoughts in mind, I started this project.

Hmm! I haven't heard of JECS before. I need to check it out :-) Thanks for the kind words!

Yes, organizing components as SoA can provide a significant performance boost in Lua, especially with LuaJIT. Both iteration and element access become faster, and it also reduces memory allocations and GC pressure when creating entities. And yes, Lua tables can be contiguous in memory if you use them carefully.

Do you have any published benchmarks?

Comparative benchmarks are a big task on their own, and usually the author's library wins in them. I have internal benchmarks in the repository, but they are not designed for comparison or for evaluation by outsiders. Maybe I'll get to that someday.

As for the SoA approach, here you can find a small and exaggerated example: https://luajit.org/ext_ffi.html
