- Prints out all the words in uppercase.
- Builds a new array of just the first two letters in each word. ("ca", "do", "av", "bo", "go".)
- Print out a row that's as long as specified. If it's a black square, print "X" If it's a white square, print "." So for an 8-long row, print ".X.X.X.X"
- A real stretch goal: put this for loop in another for loop. And print out a row for everything. So, if chessboardLength = 4, print: ".X.X X.X. .X.X X.X."
