Falsy values Memes

Ah, JavaScript's type coercion explained with toilet paper. Pure genius. Non-zero value: Has toilet paper. Works as expected. 0: Empty roll but still there. Technically exists but utterly useless. null: Just the holder. Someone deliberately removed the toilet paper. undefined: No toilet paper holder at all. Whoever built this bathroom forgot a critical component. And yet somehow all of these evaluate to false in an if statement. JavaScript, where the rules are made up and the types don't matter.
