Further Adventures

Listing 5.07 - Displaying a player's name - Task 1

Update the text logged so that it is of the form: The player's name is Kandra


var showPlayerName;

showPlayerName = function (playerName) {
    // Add extra text
    console.log("The player's name is: " + playerName);
};

showPlayerName("Kandra");
showPlayerName("Dax");

Listing 5.07 - Displaying a player's name - Task 2

Make the function show the number of letters in the player's name.


var showPlayerName;

// Include a second parameter
showPlayerName = function (playerName, numLetters) {
    console.log("The player's name is: " + playerName);

    // Show the number of letters
    console.log(playerName + " has " + numLetters + " letters.");
};

showPlayerName("Kandra", 6);    // Include the number of letters
showPlayerName("Dax", 3);

In the solution above we manually include the number of letters as an argument when calling the function.

Fortunately, all strings have a length property.


var showPlayerName;

showPlayerName = function (playerName) {
    console.log("The player's name is: " + playerName);

    // Use the length property
    console.log(playerName + " has " + playerName.length + " letters.");
};

showPlayerName("Kandra");
showPlayerName("Dax");
