826 PointsConfused about constructer scope order
In the constructer in line 4, before he started talking about naming multiple objects the same thing, (around 5:00ish) the string "name" isn't defined, so how did it compile? Or was it defined and I missed it?

Both the parameter and the reference get changed to "characterName" between 4:30 and 4:55. In between those two changes, the code would not compile. But no attempt to compile is made while the editing is incomplete.

826 PointsSo if he had tried to compile it before the change to 'this.characterName' it would not have compiled because 'name' hadn't been declared or defined before it was being used as a definition for 'characterName', but since he didn't try to compile it there and instead fixed the issue before it came up the compilation problem never came up. Am I understanding correctly?

231,265 PointsRight. in that section between 4:30 and 4:55 changes are still being made and the code isn't ready to be re-compiled yet.
