This post is part 77 of 81 in the series Programming by Stealth

My plans for this instalment were to quickly demonstrate so-called callback hell, and then move on to the solution, JavaScript Promises, but in light of some listener feedback I changed my plans a little. There was some confusion in the community about what callbacks really are, so, now seemed like an opportune moment to spend a little time re-familiarising ourselves with some callback basics. This sets things up for a bit of a teaser-ending because we’ll get as far as demonstrating callback hell, but not as far as using Promises to get back out of hell, that will have to wait until the following instalment!
