Simple script that records it's history so as not to repeat itself two times in a row...

DoNotRepeatRandomItemGetter.js

var gameMaster = "Ryanb58";
var listOfPlayers = ['Taylor','Ryanb58','Jack','John','Kyle'];
var playerNumber;

for(i=0; i<25; i++)
{
    //console.log("Current GM: " + gameMaster);
    playerNumber = listOfPlayers.indexOf(gameMaster);

    while(gameMaster == listOfPlayers[playerNumber])
    {
        //max(exclusive) min(inclusive) --> Math.floor(Math.random() * (max - min) + min);
        playerNumber = Math.floor(Math.random() * listOfPlayers.length);
    }

    gameMaster = listOfPlayers[playerNumber];
    console.log(i + ") " + listOfPlayers[playerNumber]);
}
