Null was a mistake (as per what quite a few people say) XD
Don’t know if some actual thing saying “undefined” explicitly would/could be any better, though.
There are two kinds of “null” that are often called out as mistakes, you may be thinking of. One is the null reference, as found in languages like C and Java, which Tony Hoare, who created it for ALGOL back in the sixties, has called his “billion dollar mistake”. The other is the three-valued-logic of null in SQL, which is almost as bad.
There’s nothing wrong with “null”, necessarily, in other contexts, although I do think a more clear name for whatever it means in any given context might be better.
