DOM Objects

At the very top level of the DOM object tree is the "window" object. The window object represents the browser window where the HTML Document is displayed.

The window object has a method called alert(). This method displays a popup window with the text provided for the first method "Parameter".

A parameter is a value passed to a function or method which modifies how the function or method operates.

The following Javascript can be executed before the page is loaded by using the "script" element. 

    <head>
      <script>
        window.alert("Hi!");
      </script>
    </head>
