the chores analogy makes it so much easier to understand the flow of the code

@CliffStamp 6 лет назад

This was a very clear explanation of promises that even a beginner in Javascript could understand as long as they knew/understood how to work with callbacks. Many people just right into very complicated code that beginners can't understand.

@juliofreitas1652 4 года назад

At the beginning of the video he mentioned the callback function so I saw that he had a video on this subject suggested by youtube, I paused this video and went to learn about the callback function. When I returned to this video I realized that I had used the same principle as a callback function hahah
