luajit2 VS cobweb

And Neovim is using OpenResty's branch of Luajit

Yea, LuaJIT can get near C speeds, as far as I'm aware. You can read more here: https://luajit.org/luajit.html

I also found this gtihub repo, this one is using luaJIT a just in time lua compiler, i dont know if you have any python expirience but this one, but from what i understand luaJIT makes lua a language that can be compiled and run in your terminal, it aperently also has a comminty made package/library manager called cherry.

openresty's LuaJIT2 has, and makes, regular releases (the last one was less than a month ago), and closely tracks development, including the extensions beyond Lua 5.1.

There is also the openresty fork of luajit which Neovim can be built with and provides their own releases.

Remember, bad C++ code will certainly be slower than good code written in an interpreted language! That being said, Lua is very fast, one of the fastest scripting languages. See this thread, which talks about LuaJit.

It has a few extras but they agree with the original luajit authors opinion that not every 5.2 feature can be made in jit.

That person could be you!
