How do you do the extra credit question? I'm stumped.

We've all wondered the same thing. I spent an hour trying to enable JavaScript, enable extensions, completing courses, etc, and checking each and every lesson for a link. The answer is that you don't. These are for people who are interested in the topic and who want to investigate further on their own.

In essence, the reward is in the expanding of one's knowledge.

It may be less confusing if these were labeled "Extra Work that You Can Do if You Are Interested but for which You Will Not Receive any Extra Points." My guess is that this is too verbose and that the focus group preferred "Extra Credit" to "Extra Work" as the former sounded like ... well ... too much work without enough credit.

There are a few ways you can approach to solve this. Without giving you the answer directly maybe I can help guide you to the solution with a few steps.

The first step would be to review the video for any clues to how this is done programmatically. Second you can refer to your Help and Documentation guide within Xcode by researching any methods related to the task described in the extra credit task description. Thirdly you can also refer to the Apple Developer website. There are many useful guides that can help you accomplish certain task.

This may seem like a lot of effort but the pay off is learning through your experience and the satisfaction of knowing you did it on your own without being shown. The funny thing about programming is that sometimes there are several ways to solve a problem. The real extra credit is in figuring out how many ways a problem could be solved and which of those ways is actually the best practical solution.

Troy: I think that you may have posted this answer to the wrong forum item.
