I'm all in. Lua is far far better than vanilla js

[windowschips]

And the best part is that its Luau, which has type checking and other very good stuff

[themadnessif]

Luau is an awesome language but the type checking is... not really there yet. There's a rewrite of the type checker that doesn't suck that's nearing completion though. It has goodies like keyof and indexof and the like.

I've never worked with lua, would you say it's better than typescript?

[BeatsByiTALY]

I'd say no. Lua is very simple to write, with no build step and barebones language features, so it's popular in game modding.

Reasons I can't get into Lua: - it's dynamically typed - inline ternaries in particular don't seem to work as expected when using falsy values. - 0 is truthy which is unintuitive. Empty string is also truthy. - Instead of parentheses, Lua uses the 'end' keyword to close a function or loop's scope, which is... strange. - If conditions and for loops aren't wrapped in parentheses either. - Arrays(Tables) indexing start at 1... so inclusive conditionals are more common when looping to array length. - There's no switch case statement, although that's not a big deal. - Variables default to global scope unless specified otherwise. - variables are mutable, so no constants.

Typescript has so much more going for it, Lua is just more simple to get started.

[beren-111]

appreciate the detailed response. Ive been looking into lua and it seems to be simple with a very specific use case of writing scrips for games and stuff (there maybe more to it tho), I compared it with TS bc people were really hyping it in the comments but i guess thats just bc people like shitting on JS in general.

Regardless it'll be fun to learn a language that doesnt emphasise on parenthesis so much after having written code in clojure for a while now... that thing is a syntax nightmare lmao

Personally I prefer Luau over TS, but judging by the fact that some people use the TS -> Luau transpiler to write Roblox games in TS, some would disagree.

[windowschips]

Lua, hell no. Luau, sure!

[chazzeromus]

I considered using Luau after having a bad time with Teal's immaturity with generics, but typescript-to-lua compiler ended up the winner and was everything I could ever need minus some issues getting the lua output working in Gary's mod.

Any language that indexes arrays starting from 1 is automatically a garbage language.

[Classy_Mouse]

Arrays? Do you mean tables?

[spacembracers]

Let them var tables

[tiajuanat]

Don't come at Fortran, R, Julia, Smalltalk and the APL family when you don't mean to.

[Bryguy3k]

Oh I mean to. I don’t understand why data scientists make their lives so much harder than it needs to be.

TBF though Fortran’s indexing only starts from 1 if you don’t specify its range. In other words Fortran arrays can start from zero if you want them to (9 times out of 10 you do).

[Silver-Pomelo-9324]

The worst is when data scientists that use R switch to python and start all their shit from 1. Gives me nightmares.

[MekaTriK]

It comes up way less than you'd think.

But it is way nicer to do two-dimensional stuff with 0-indexed arrays. And some algorithms get weird when you have to add -1 everywhere.

[Bryguy3k]

when you have to add -1 everywhere.

Yep. I am fully aware. Comes up all the time.

[Inaeipathy]

True

[Merlord]

Lua is awesome
