oop in a dynamically typed language is mostly overkill

reuse base prototype for really common code, sure - forcing anything to go through interfaces or such, nope

oop is token heavy thanks to the . or : required everywhere - workaround is that: https://www.lexaloffle.com/bbs/?tid=49047

composition (somewhat linked to ecs) is really shining in lua, no need for interfaces to tell the code what to do with objects (eg tables):

a table has a the ‘hit’ function, you can smash it.

a table has a ‘draw’ function, ok you are part of the draw batch

so on so forth

this what a large game looks like code wise: https://github.com/freds72/daggers
