How do I get length of a table/array without using # or table.getn() ?

Asked Feb 11, 2018165 views1 answers

I want to get length of an array/table.

local mytable = {one = {value = 1}, two = {value = 2}}

print(#mytable)
print(table.getn(mytable))

Both will return 0. I want to find the way that will print 2 in this situation.

You can't use the length operator on dictionaries, you'd have to loop through it.

local mytable = {one = {value = 1}, two = {value = 2}}

local function countNumberOfIndexes(thisTable)
	local count = 0
	for i,v in pairs(thisTable) do
		count = count + 1
	end
	return count
end

print( countNumberOfIndexes(mytable) )
