0? Because Lua isn't C. It makes sense for C to treat 0 as falsey, because (void*)0 is Cs way of expressing a nil-value, as well as not having a dedicated boolean value to keep the language simpler.
Lua, both has a dedicated nil value and a boolean type, so there's no reason whatsoever to treat zero as falsey, other than the C cargocult.
As for empty strings, I really don't see the rationale behind it. An empty string is not nothing. At the very least, it still holds the length-data of 0, so it's conceptually more than just nil and should thus still be truthy.
