Purpose of (message)?

Why does Dave include (message) in his function? Why wouldn't this work?

The document.write() method takes whatever you pass in as an argument (within its parenthesis) and writes that to the page. If you don't pass any argument then it simply blanks the page. So he defines and uses the message parameter so that he can actually pass some data into the function to be used with the document.write() method.
