The Parentheses Paradox

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.
