Are you saying that because (JavaScript!) functions have a "length" property representing number of arguments, they are all O(N) (or greater)? (btw I don't see how "this" fits in here.) The only way I can see it making sense is because a function could take arbitrarily many arguments. Why on earth would that matter if the function doesn't do anything with those arbitrarily many arguments? We may not know in advance what a caller gives to a function, but of course we know what the function does with its arguments--it's a function's body that we're analyzing and classifying a Big-O for!
