In Smalltalk it is called nil. nil is an instance of the class UndefinedObject. In principle you could subclass UndefinedObject. But what is interesting is that you can add more instance methods to the class UndefinedObject so you could define the method #isNil for instance which could be defined also for all objects, but differently

Back when I was a network engineer I liked to imagine that I sent a lot of bad traffic there.

Also, null might be the empty string, but when is it ever zero?<p>Edit: this is a serious question.

It would be cooler to call it Fernando Poo[1].<p>[1] <a href="https:&#x2F;&#x2F;illuminatus.fandom.com&#x2F;wiki&#x2F;Fernando_Poo" rel="nofollow">https:&#x2F;&#x2F;illuminatus.fandom.com&#x2F;wiki&#x2F;Fernando_Poo</a>

Each language can define NULL differently. However, because eventually it gets compiled to machine code, it does indeed need to be represented by some value. Most languages represent that value as 0, but not always.<p>It&#x27;s better to think about NULL as a value plus a type. The value &quot;False&quot; may be 0 with a boolean type, just as NULL may be 0 with a pointer type.
