Rock Paper Permutation

rockPaperPermutation.js

/*
* Write a function that generates every sequence of throws a single
* player could throw over an n round game of rock-paper-scissors.
*
* For 3 rounds your output should look something like:
*   [["r", "r", "r"],
*    ["r", "r", "p"],
*    ["r", "r", "s"],
*    ["r", "p", "r"],
             ...etc...
     ]
*
*   - Make your function return answers for any number of rounds.
* Example:
* rockPaperScissors(5); // => [['rock', 'rock', 'rock', 'rock', 'rock'], etc...]
*
