I've built something with Lua because the lovely Love2D game lib prescribed it. I hated almost everything about it (globals, stdlib, silly typing discipline, debugging, syntax). Rewrote the whole thing (when it was small) to Kotlin and libKDX (a wrapper over libGDX). Experience was so much better it's not even funny.

Lua felt like JS and PHP had a secret child they abandoned and somehow survived up growing up in a dumpster.

I know I should not bash open source software: I know it takes a lot of work to build/maintain it. I'm merely reacting to this post.
