/*Refactor and Reflect
This challenged really helped me gain more confidance with javascript and specifically syntax and for/for..in loops;
That said, although I tried to refactor, I don't know how DRY or good my code is--there just seems to be so much to 
learn in JS and it seems overwhelming to tackle, especially because I don't know exactly what to focus on for our purposes. 
Having the bit of background that I have in Java does help a little the the syntax and loop logic.
