    By far, the best explanation of Promise. Breaking everything by details, you also mentioned that resolve and reject are functions, not just arguments, and you pointed out that massages of resolve and reject are automatically passed into functions inside then and catch, lot of people ignoring those parts when explaining Promise which leeds to confusions. Great job.

    Exactly right. I, too, listen for accuracy in an explanation and observed in addition to these issues that he explicitly said there is one argument to the constructor "A function" containing two parameters. I have heard others say there are two parameters to the constructor. Best explanation.

    I literally quit learning javascript three times after hitting a wall not being able to understand promises until I found (but really, searched for!) this video. Out of every learning resource, bootcamp, course I’ve taken this is the only video that has succeeded in clearly explaining the nature of how values flow from the promise to the callbacks. I don’t know why other instructors don’t take the few minutes it took you to explain that resolve and reject are methods and that they are actually doing something instead of leaving students wondering how the heck an external function is magically receiving values that shouldn’t be within its scope!! Thank you sincerely for your outstanding pedagogy. I wish you and your channel nothing but success and thank you for bringing me peace of mind. It is so incredibly frustrating to go from confidence and order learning everything and then suddenly hitting a topic that seems to at first glance to a new student appear to involve multiple concepts that were not previously taught, but now you’ve helped me see the relationships are coherent.

    Tried to learn about promises when watching several different videos about a couple weeks ago. Got frustrated and put it aside. Found this one today and it taught me in 15 minutes what probably 45 minutes of other videos couldn't make as clear. Thank you so much for you clear and informative explanation!

    Starting around 13:15, *The message displayed at the bottom of the video screen for the "reject" case is wrong* : It should be 'Not bringing tacos. Food truck not there.' but the video shows 'Cannot bring tacos' Of course, this is just a tiny careless error. Thank you for this good tutorial.

    I did have a question on something I didnt understand , if anyone could help. When he said that resolve and reject were arguments of the function inside new Promise , are they actually parameters. I was confused by this because you change the (resolve, reject) into anything and still get the same result. So it seemed like there were two different versions of resolve and reject. One that is only the placeholder or parameter that can be named anything / and Two being the actual method that is being called when the promise is running. Do I have that right , I cant seem to figure out how else one can explain how the parameters ( resolve, reject) can be changed to any other word while still getting the same result.

    When you have to go to the college but you realise you won't make it in time of attendance roll call and you ask your friend on phone to mark present in the attendance for you. He's being a proxy for you at that moment. Now the defination again: "A promise is a proxy for a value that will eventually be available" > Promise is your physical presence in the school > Proxy is your friend marking the roll call for you
