Change the message in the parentheses when showMessage is called.

};

showMessage("We choose to go.");    // Change the message

Add two more calls to the showMessage function with different arguments each time.

var showMessage;

showMessage = function (message) {
    console.log("The message is: " + message);
};

showMessage("We choose to go.");

// Call the showMessage function twice
showMessage("It's full of stars!");
showMessage("I'm going on an adventure!");

showMessage = function (message) {
    console.log('"' + message + '" is the message.');
};

showMessage("We choose to go.");
showMessage("It's full of stars!");
showMessage("I'm going on an adventure!");
