@ewitkowski, I hope I can help you a little with your questions.
I went into the code studio for unit 6, lesson 8 and I was able to find teacher answer keys for several different levels. The final level (13) has an Example Solution when you open the teacher panel (as long as you are signed into a teacher account). (See screenshot below).
As far as the difference between the “getters” and the “setters”, getProperty retrieves a stored value (for use somehow) and setProperty assigns a value to a property to store it for later use.
There is an explanation on W3Schools here. It doesn’t use the exact terminology as appLab, but it does illustrate the difference.
Is that what you are looking for? If not, I know we have some creative teachers in the forum who can explain how they teach this in their classes.
If this doesn’t help or if you still can’t find the answer keys, please respond and we can try again!
thanks,
Mike
