Talk:Learning Petit Lesson 4: Arrays/@comment-5334617-20141208132852/@comment-25827645-20141208133526

I heavily considered replacing INDEX with NUMFRIENDS; what you wrote there is exactly how I would write the code, but I felt that would be less clear for a rookie and ended up leaving NUMFRIENDS to the tip. However, I stupidly forgot to include a return at the end.

I'm going to add an Advanced Arrays tutorial later that will cover "dynamic" arrays and related topics in more detail.
