Can confirm, async programming - whether done with callbacks/promises/sugar is tangential here - is a conceptual stumbling block for some at first, and that includes smart programmers who haven't done much in terms of Web or GUI programming. Add the concept of static scoping and closures and you have a few things to absorb first, before you get comfortable. It has to click. Reminds me of stochastics in school, which was a subject that wasn't immediately natural for some who were otherwise very good at math in general. For me it's bit fiddling for example: I bought Hacker's Delight some months ago and first had to really work through even the most basic things on paper until it stopped to feel like magical hieroglyphs.
