👉 A non-existent or empty value or set of values.
Alright class, settle down now, let’s talk about “null.” It’s a tricky word, a bit of a stall, Like an empty space within the hall. The dictionary's right, you see, it’s true, “Null” means nothing , nothing new! It signifies that something isn’t there, A missing value, beyond compare. Think of it like this: a box with no toy, Or a seat in the theater – empty and coy. It doesn't mean “zero,” don't you see? “Null” is absence , completely free! Sometimes in coding, a variable might wait, But haven’t been assigned a value at all—that’s fate! We might set it to "null" to let the program know, “There’s nothing here, don't you go!” Do you have any questions? Let’s discuss this further, and make sure you understand.
