Null-vs-zero Memes

German developers trying to explain to their manager that 0 and null are totally different things, but corporate just sees two empty values and shrugs. The title "Kay Jass Nummer Null" is a phonetic German pronunciation of "case number 0" which is *chef's kiss* because it sounds like someone desperately trying to explain JavaScript type coercion to a non-technical audience. In JavaScript, 0 is a perfectly valid number that exists, while null is the intentional absence of any value. But try explaining that to someone who thinks they're both "nothing" and watch your soul leave your body. It's like explaining that an empty box and no box at all are different concepts—technically correct, but good luck getting that approved in the sprint review.
