I think this article could potentially “misteach” people to create types like `nullableUndefinedString` when you could mostly use `argOrProp?: string | null`.
Also, there’s no need to use strict types checks for null and undefined when you could check for both like `value == null`.
Regarding nullableUndefinedString, you’re right and, as a matter of fact, it was just an easy way to define a single type used throughout the entire article without repeating it meaning every time.
strictNullChecks, on the other hand, is recommended by the documentation itself. Hence, even if there are other ways in the language to achieve the same result, to me, the pros of that flag outweigh the cons.
