Arrow functions Memes

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?

Looking at ( ( ) ) => { } ) ( ) ; and wondering how it works is like staring into the abyss of JavaScript's syntax flexibility. It's just nested parentheses, curly braces, and arrows having an existential crisis together. After 15 years of development, I still get cold sweats when I see code like this in production. Somewhere, a senior dev is nodding knowingly while secretly Googling "what does extra parenthesis in arrow function do" in an incognito tab.

I see we've discovered the elusive "filterception" in the wild. Some brilliant mind decided to filter the filters with a filter that filters filters. And they even helpfully commented "// filter" at the end – you know, in case the five other instances of "filter" weren't clear enough. This is the coding equivalent of saying "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" and expecting it to make sense. Somewhere, a code reviewer is staring at their screen, questioning their career choices.
