/* FreeCodeCamp - Nesting For Loops Challenge.
                                                              Total: 75 Lines on Gist.
Before we get into the challenge instructions and process,
I'd like to have an extended review for Accessing Complex Arrays &
iterating across arrays using for loops. Then we'll move into the complex arrays.

For this process, let's first create an array:
var arr = ["B", "D", "F", "H", "J", "L"]; // Even letters.
To access "B" we use arr[0]; and "J" is arr[4];
