You know you're in trouble when someone shows you ( () => {} )() and asks "what does this do?" The dreaded immediately invoked function expression (IIFE) – that beautiful monstrosity that executes the moment it's defined. Vibe coders are too busy shipping features and copying Stack Overflow snippets to worry about these syntactic gymnastics. They see those parentheses wrapping an arrow function, followed by execution parentheses, and their brain just... bluescreens. Meanwhile, the interviewer is sitting there waiting for you to explain how the outer parens turn the function into an expression so it can be immediately invoked with () . The semicolon at the end is just chef's kiss – because nothing says "I understand JavaScript's automatic semicolon insertion quirks" quite like explicitly adding one after an IIFE. If it works, it works, right?

Ah, the beautiful absurdity of JavaScript! The expression (() => {})() transforms into {} followed by () and a semicolon. It's literally an immediately invoked function expression (IIFE) that returns an empty object, which then gets treated like a function call, followed by a completely disconnected semicolon. The beauty here? This syntactically valid gibberish does absolutely nothing useful. It's like building an elaborate Rube Goldberg machine that just turns itself off. Peak JavaScript moment where you can write code that's simultaneously correct and completely pointless. No wonder the poor soul is questioning their reality!
