Module:Util/tables/len

len(tbl)

Returns

• The length of the array component of tbl. Unlike the # operator, this function works with frame.args and tables loaded via mw.loadData.

Examples

#	Input	Output	Result
1	len({1, 2, 3, [10] = 10})	3
2	len({ foo = "bar" })	0

local function len(tbl)

	for i in ipairs(tbl) do
		count = count + 1
	end
	return count
end
