Then maybe you&#x27;re a programmer that was so gifted you didn&#x27;t have to learn like the rest of us (with hello world and simple number guessing games).  If so, I completely understand why you would have the impression that simple demo code isn&#x27;t necessary and everyone should just jump right into codin&#x27; apps.  Sorry for the burn.  You should be aware that basic demo code has quite a bit of intrinsic value especially when the users are free to try it out on their own.
