table.insert adding a unknown table

Question

So im trying to add a table inside another table but each time i do it, it adds a "1": from nowhere...

my code :

local previousClothes = json.decode(xPlayer.get('clothes'))
print("old previousClothes"..json.encode(previousClothes))

local clothes = {[label] = {[parentName] = parentValue, [partName] = partValue}}
print("old clothes"..json.encode(clothes))

clothes[#clothes+1] = previousClothes
print("new clothes: "..json.encode(clothes))

xPlayer.get('clothes') = my clothes stored in my db

local clothes = my new clothes received in the function/event

and here comes my issue.. it adds a "1": to my table

Your clothes is not an array. It contains key-value entries. So, JSON treats it as dictionary (object) instead of as array. — Egor Skriptunoff

I don't see a problem here. Lua tables can be arrays and dictionaries simultaneously. JSON objects can not. Why do you use JSON repesentation to display Lua tables? — Egor Skriptunoff

Instead of adding previousClothes as an array element to clothes, you can copy key-value pairs of previousClothes into clothes.

for k, v in pairs(previousClothes) do
    clothes[k] = v
end

I assume this is what you want.

Because Your clothes is not an array, see the documentation in here. When you use # get a table length, it is better to be an array.
