var players;
var showArguments;

players = [ "Dax", "Jahver", "Kandra" ];

showArguments = function (item, index, wholeArray) {
    console.log("Item: " + item);
    console.log("Index: " + index);
    console.log("Array: " + wholeArray);
};

players.forEach(showArguments);

Listing 8.09 - Using the arguments passed by forEach - Task 1

Add two more names to the players array.

var players;
var showArguments;

players = [ "Dax", "Jahver", "Kandra", "Blinky", "Boo" ];

showArguments = function (item, index, wholeArray) {
    console.log("Item: " + item);
    console.log("Index: " + index);
    console.log("Array: " + wholeArray);
};

players.forEach(showArguments);

Listing 8.09 - Using the arguments passed by forEach - Task 3

Change the first console.log so it uses wholeArray and index to display the current item in the array. Don't use the item parameter.

var players;
var showArguments;

players = [ "Dax", "Jahver", "Kandra", "Blinky", "Boo" ];

showArguments = function (item, index, wholeArray) {
    console.log("Item: " + wholeArray[index]);
    console.log("Index: " + index);
    console.log("Array: " + wholeArray);
};

players.forEach(showArguments);
