Isn't the undefined one incorrect? From what I know undefined means it can contain whatever value. So it could be no toilet paper, full toilet paper or anything in-between.

not undefined in mathematics, an undefined variable is just a variable that hasn't been defined (yet) and is therefore nonexistent

Depends on what undefinedwe're talking about. JavaScript undefined is just a value for undefined variables. In C undefined behavior could be anything, ranging from reading in random garbage to time travel or summoning eldritch terrors.

This is JavaScript undefined specifically where it refers to a key that isn't present.
