Arrow functions Memes

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.
