Thank you! But the fact is that for example, for divs or bootstrap or other topics, there were 100 challenges each, teaching you about every symbol, why it goes somewhere and not the other way around, etc. But on this quite heavy topic, jQuery and JSON it’s like “Here is the code you need to put in the challenge to move on :” and there’s the code for me to copy-paste, There is no explanation, no in-depth knowledge and I can not go on the forum/chat and ask all pretty dumb questions like the one I just asked here - and they are dumb because I shouldn’t ask each detail on a forum, I should learn them on a course, all at once, in a couple of hours or a day, instead of spending 2 days to research apis and waiting for answers.
I started watching the videoclip mentioned above in the list of resources and I finally found out what $ is!!! I didn’t even know that. I didn’t know when you use it and when you don’t. It’s the way you call a jQuery. I had no idea!
