Bart Busschots (successfully) explains the concept of JavaScript promise chains. It’s a rough ride because of the subject itself, but he gets us there through his care and detail in explaining the concepts and of course his great examples. When he’s done, you’ll know how to chain promises together, you’ll understand what data is passed through, and you’ll understand why he says, “Don’t have unhandled rejections, it’s just not nice.”
