dont understand promises.

Steven Parker i came here from the https://teamtreehouse.com/library/ajax-basics/programming-ajax/working-with-the-fetch-api section of the course.

Having a hard time understanding promises. Should i end the ajax basics first and then try to come back here if i can understand correctly. this workshop doesnt looks like its for starters. what do you say? is it good if i do it like that?

Well, I know this is late but I just wanted to tell you that, you're not alone, promises where hard to understand for me too and other programmers. What I did is I searched youtube for 'javascript promises' and found an awesome tutorial explaining promises in in a really simple and friendly way. I think maybe treehouse made this for more experienced programmers or something, I don't know. However, the teacher gave good examples. This is the tutorial on youtube if you would like to watch it https://www.youtube.com/watch?v=QO4NXhWo_NM&list=PLRqwX-V7Uu6bKLPQvPRNNE65kBL62mVfx. I didn't watch all of it, just watched till the point where I can understand what's going on exactly in this workshop. Hope this helps :)

Perhaps "a day or so" was a bit of an underestimation. I guess sometimes it might take a few months to get the answer you really like. :laughing:

:bell: I was alerted by your tag, but there are many folks here willing to help. When you ask a question, try giving folks a chance to answer (a day or so) before asking or tagging someone specific.

I think you can probably complete the "fetch" workshop without completely understanding promises. You could do the promises workshop afterwards. But if you prefer, you could do them in the opposite order; I don' t think either one is dependent on the other.

I don't see how this can be complicated as it's almost like an if else statement unless you want some deeper meaning of things.

  1. Create promise object with a resolve statement
  2. capture value with a chained .then statement

As simple as that is all we need to know?
