Hi,
Thanks for the feedback. I am reviewing questions currently, this is the initial release. Over the coming weeks I will be changing the vast majority of the questions to reflect the difficulties better and adding more and also be getting some contributors to help hopefully :)
Yeah, actually apart from those 2 moments, the tests are OK.
Ah, about setTimeout in a loop - better write something like "nine times 10" and "ten times 10" instead of making people count tens "manually".
