Asynchronous JavaScript #4 - Promises

Yo ninjas, in this asynchronous JavaScript tutorial, I'll introduce you to promises. JavaScript promises are like placeholder objects for an action that will complete at some point in the future, and are a great way to organise our asynchronous code and callback functions.

Big props for taking the time to cover the inside story so we understand what's going on under the hood. You always provide just the right amount of detail, most videos are either provide too much detail or not enough.

Great tutorial! The part where you say that promises are a placeholder for the result of an asynchronous action helped me fully understand the concept, as well as appreciate the usefulness of promises.

Thank you so much for this video. I was pretty frustrated today because of the callback hell and didn't quite understand promises before. This cleared so much for me in 13 min. :)
