I am currently trying to learn what are Metatables and how to use em, but I am thinking of when to use them after learning, and are they even useful?
Any help is appreciated!
Metatables can be incredibly useful, especially when designing OOP systems. They allow you to define custom behavior for tables, like how they should react when certain operations are performed. The most common of these being __index. When a table is accessed and the key doesn’t exist, the __index metamethod allows you to either return a table or do something with that index. This is useful for things like inheritance, where child objects can inherit properties from a parent without duplicating data.
