//
// The "switch" statement lets you match the possible values of an
// expression and perform a different action for each.
//
// This switch:
//
//     switch (players) {
//         1 => startOnePlayerGame(),
//         2 => startTwoPlayerGame(),
//         else => {
//             alert();
//             return GameError.TooManyPlayers;
//         }
//     }
//
// Is equivalent to this if/else:
//
//     if (players == 1) startOnePlayerGame();
//     else if (players == 2) startTwoPlayerGame();
//     else {
//         alert();
//         return GameError.TooManyPlayers;
//     }
//
