Further resources for JSON APIs and AJAX?

I was having fun being challenged a bit with ‘Basic Algorithm Scripting’ section.

But now the ‘JSON APIs and AJAX’ section just seems like cut and paste.

What other resources are good to learn these topics further?

I meant I enjoyed ‘Basic Algorithm Scripting’ Section , but its the ‘JSON APIs and AJAX’ section thats copy and paste. I will edit the post to show this.

I see. Okay I’m ganna go learn AJAX with JavaScript without jQuery for now.
Then I’ll come back to do these challenges.

Thank you for letting me know the intention of this section
