Awesome video, thank you so much. Trying to understand promises without first understanding callbacks is an uphill battle. Appreciate the "from the ground up" explanation.

Awesome video, but I stopped the video two times to check where the notification voice is coming from !?
Finally, it's in the record :D

Yeah, there is definitely a point where nested callback functions and callback calls starts to really gum up my brain.

You say its an asynchronous event because when geolocation returns from execution it will call one of those functions, but if its asynchronous shouldn't both functions, the geolocation and either the success or failure run at the same time?
