luajit2 VS fengari

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.

luajit.org said

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.

it should be possible, the article mentions https://fengari.io/ (a Lua VM written in JavaScript)

Check out Fengari or Lapis. Fun fact: itch.io is written primarily in Lua, and started by the same person who made Lapis and MoonScript.

I was real excited to see these recently... have you tried any? https://fengari.io/ is the one I was most intrigued by.

Hello, there is also fengari: https://fengari.io/

Other languages have done that :)

Lua in the browser: https://fengari.io/

And then you can use that to run Fennel, a Lisp that compiles to Lua https://fennel-lang.org/

I think TypeScript also has a script you can include that lets you put your TS code in a special script tag, and it gets compiled in-browser.

just use lua, it’s what should have been used for web scripting anyways

Please stop this stuck in the mud nonsense. Anyone stumbling upon lua.org might think the project is dead already. The material is great, close to the best, but its presentation is pure shite. Not mobile friendly (what kinds of device do you think the majority of people in the Global South use?). We live in a world of code highlighting, none of that in PiL. We live in a world where Fengari allows Lua to run in the browser, does that make an appearance on lua.org, allowing users to immediately play with the language? Of course not! It's almost as if the Lua team is trying to push away potential users.

why not use lua

Just use lua https://fengari.io/

Definitely the most surprising use-case for Lua that I've seen is http://lua.space/webdev/why-we-rewrote-lua-in-js which discusses https://fengari.io/.
