| * If you have to validate arguments, use the built-in checkArg method. Homogenous error messages are a good thing! Its usage is checkArg(n, value, type1, ...), where n is the number of the argument, value is the value of the argument and type1 and so on are the allowed types for the argument, as retrieved via type(value). The number is used in the error message like so: "bad argument #n (type1 expected, got type(value))". So for example, to require the first argument to be a number you'd do checkArg(1, arg, "number"). | * If you have to validate arguments, use the built-in checkArg method.
