this is what a deep copy function is supposed to look like, right? i'm not forgetting something obvious?
function deep_copy(other)
if tostr(other) != "[table]" then
return other
end
t = {}
for k, v in pairs(other) do
t[k] = deep_copy(v)
end
return t
end

Looks conceptually right, but some implementation questions:
What language is this?
Does your language have any notion of types? Looking for [table] as a string is sketchy. What if your value is the literal string [table]?
If you have an array, is the "return other" going to return a copy of the array, or a reference?

@polyphonic haha i actually just updated it to check against 'type' instead of 'tostr'; this is lua and that part SHOULD work. i'll try it aggain with the type check

I suspected lua. Lua is pretty cool!
It can easily be confused with javascript, especially when you have to deal with them both.
Except lua is actually nice under the hood! 😅
Looking up lua specific examples, you still have corner cases If your table is cyclical or recursive. Also you haven't covered metatable copying.
But I suspect you don't require these features today.
