No. In javascript pretty much all arguments are optional, if they aren't assigned in the call they will have a null value (which may be a problem it the function assumes it will not be null), if they aren't used by the function, they aren't used by the function. This notation means that the function will do something reasonable if the argument is null (in most cases).
