This was intended as a meme but is actually a good representation of what "Null" is. In C#, when you declare string s = "My shit"; it means that "s" is a reference to a memory location that holds the data "My shit". string s = null; means that the reference "s" exists but it's not pointing to any object, as in it holds nothing.

March 21, 2023Why the hate for null?
Null pointer exceptions are annoying but so is having to constantly check every object Very few values in your program actually need to be nullable, so you only need to check those places where they are. And you should be checking those places anyway! Edit: Note that you might be missing the important fact that you need some way for the compiler to remember that you've done the check. You can do this by pattern matching or flow-sensitive typing, for example. But yeah, this means you don't have to keep going back to check, which would be super annoying! It's also a shame to see the level of negativity in the other comments. It's really useful to hear perspectives like this, because it helps us see how other people might misunderstand what we are doing, and can help improve our explanations. Let's be a little friendlier please! :) More on reddit.com

NULL is nothing. It means theres nothing there. Often its just a place holder before something is there. Say u have a bunch of variables of animals. U might set them to NULL before u know what they are. Then u might check if they are NULL before u add an animal to them. Things are initialized as NULL.
