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 clone = require("Module:Util/tables/clone")

local function len(array)
	-- The # operator won't work on tables loaded via mw.loadData so we have to clone them first
	return #clone(array)
end

return len
