23,932 PointsCharting flow of callbacks on pen and paper?
Hopefully not a silly question but I had a hard time following without mapping everything out on paper with pen.
Do professional developers do this? Or is it better to stick to dev tools?
I hope to get to the point where I can follow only using dev tools.

Use the tools that work best for you, without concern for their being physical or virtual.

For those banging your head against a wall right now and wondering about sketching out the flow or how you'll ever get used to this, be aware that you're about to be introduced to more modern asynchronous approaches using Promise based code. It's much easier to read, especially the final form of async/await, and will make you feel much better about getting into asynchronous programming. In hindsight, I do appreciate how we were introduced to callbacks first here so that we understand what's going on beneath the sugar. If you're struggling with this particular section like I was, just stick with it and move along.

I was also thinking about mapping out the flow with a pen and pencil. I'll definitely give that a go!

Full Stack JavaScript Techdegree Graduate 16,968 PointsWow.....I'm totally lost trying to follow this. I thought I had a handle on Unit 5 until I hit this spot. I've watched the video several times, followed the links to read other sources and still no better. I think I will revisit this first thing tomorrow morning as I am just not getting it even a little bit right now.
