Everything Is An Object

JavaScript devs discovering that literally everything inherits from Object.prototype: strings, numbers, booleans, arrays, functions, even null and undefined (well, almost). You think you're working with primitives? Nope, they get auto-boxed into objects the moment you call a method on them. That innocent "hello".toUpperCase()? Your string just became a String object behind the scenes. JavaScript's prototype chain is like that friend who insists everyone at the party is related somehow. Try typeof null returning "object" and watch the existential crisis unfold. The language took "everything is an object" from Python and Ruby, then cranked it up to eleven with some delightfully weird type coercion sprinkled on top.
