/* Further Adventures
*
* 1) Add a fifth score to the array.
*
* 2) Add an extra console.log to display the new score.
*
* The index of the last element is one less than
* the length of the array.
*
* 3) Log the value of the last element to the console.
* Start the message with "The last score is " and
* concatenate the score to the string.
* Use an expression involving scores.length
* as the index for the last element.
*
* 4) Add an extra score to the array and
* run the program again.
