Break the Hello World! message across two lines.

    console.log("Hello\nWorld!");    // Use a line-break
};

sayHello();
sayHello();
sayHello();

Listing 4.06 - Calling the sayHello function three times - Task 3

Create a function that prints the letters of "Hello World!" one by one down the page.

var sayHello;

sayHello = function () {
    console.log("H\ne\nl\nl\no\nW\no\nr\nl\nd\n!");    // Use line-breaks

You could also use a separate call to console.log for each letter.
