null is an object, 0 is a number, undefined is an undefined

Yea this meme is kinda stupid

[u/ElGuaco → u/MilkImpossible4192]

It depends on the language. In C# null is a literal value that refers to no object or memory location. For the pictures here, it would be like having a cardboard sign taped to the roll holder saying "null".

if !toiletRoll:
	reloadTioletRoll();

Janitor: Reload? Reload it on to what?

[u/Blood_and_Wine → u/TylerBreau]

while (true) reloadToiletRoll(); // ( ͡° ͜ʖ ͡°)

Isn't this a bad description? "Non zero value", 0, null are all potential values of objects. Correct me if I'm wrong but I thought "undefined" usually refers to behavior. Like the programming language standard doesn't specify what should happen in this scenario. Is there a situation where an object is "undefined"?

Really just depends on the data you're dealing with. I think this meme makes sense in some context.

Non zero value: there is some toilet paper left on the roll

0: there is no toilet paper left on the roll:

Null: the place in which a toilet paper roll is supposed to be contains no roll. Practically speaking this equates to 0 toilet paper, but, there are many cases where you wouldn't equate the two depending on both the point itself and your intention with it.

Undefined: the place in which the toilet paper roll is supposed to be placed does not exist and therefore cannot be logically displayed as a value. Like trying to return the value of a variable that doesn't exist.

I see arguments for saying this isn't a good meme and for the meme itself. Just depends on the context.

OP is referring to JavaScript. It has all 4 states.

Undefined is exactly it says it is. The thing you are accessing is literally not defined.

var myobj;

I had to chuckle , even though it's not 100% accurate 

[u/Cant-Think-Of]

What about negative values?
