I left a job where I'd built a simple UI to a complex back-end using jQuery. A former co-worker told me the guy who'd taken over that project kept complaining that he didn't understand "all this JSON" in the app. Friend: "Can I see some of the JSON?" In-over-his-head Developer: "Sure, here." Friend: "That's not JSON, that's jQuery." Dev: "Whatever, it's the same thing." Friend: "No it's not and you thinking it is, is the real problem here."
