Ooh and the edge cases. Like if your last name is Null.
Bobby Tables would be proud.
The way I use it is 'undefined' is literally undefined (not set), but null means no value - explicitly.
I used to ban
nullusages with ESLint rules for this exact reason. If it’s there use a value, if not useundefinedExcept you can define a value with undefined and accessing that value will have different behavior than attempting to access an undefined value.
It's a non-zero string tho?
