[chatmasta]

It’s really much more like JavaScript (due to its prototypical nature), where “everything is an object” is effectively saying the same thing.

It's much more like JS without all the prototype stuff.

Aren't Lua metatables and JS prototypes almost the same mechanism?

I say almost, because I think metatables are more broad than JS prototypes - you can emulate JS prototypes behavior using Lua metatables[0], but I don't think the reverse can be done (maybe with some Proxy[1] hackery?).

Yes, you're right, `__index` does behave a lot like `__proto__`. I often forget that it is one of the few entries in the metatable that doesn't have to be a function.
