I found some errors in the Get It? section questions. In the last section of promises, 3_10_13, question 2 shows there is only one correct answer — .catch(error=>console.log("error caught")) — but the explanation indicates that you can also use the "then()" function to capture the success and error, or you can use "then()" with the success not defined. So I think the correct answer should require three of the options.
Question 3 has a typo: it asks "What to you expect..." instead of "What do you expect..."
In section 3_11_2 (the second section of Generator Control Flow), the explanation says "it prints out 2 and 3" (after initially printing "a") whereas the first sentence and third answer option say it prints ' "a," then "2," then "c," then undefined.' So from the explanation it can't be ascertained whether it prints "a, 2, 3" or "a, 2, c."
