The semantic of undefined in JS means nothing is even passed (judging from how it usually appears and how it interacts with other language features). null in typed language (especially OOP languages) usually means bottom. So it really depends on what this input validation is even supposed to mean. Is the input not provided, or is it a bottom that is created by the caller's code?
Also, empty string results in empty array is the natural behaviour, I'm not sure why it's mentioned in the first place.
short and sweet!
