This is a very short one. I have looked at so many languages lately looking for something to compliment my JavaScript and node stuff. Something that can be used by WASM and also doesn't feel a million miles away from JavaScript.

Lua has first class functions!
Lua has only one multiple data storage type, the table. It's like an array, it's like an object literal.
Lua is tiny I mean fit on A4 paper tiny.
Lua has a package manager which is actually good "Luarocks"
Lua is fast, it's the fastest scripting languages.
Lua is used in famous projects from World of Warcraft to Nginx server.
Lua is also an Application language.
Lua takes around an hour to learn.
Lua has require like node

Lots lots more, even things you didn't know you wanted.

Give it a shot you may be astonished.
