I am not quite getting the purpose of function print(message) { document.write(message); }

What is the purpose of

function print(message) { document.write(message); }

if anyone can clarify that would be great

In this case, I think it just looks nicer. Or he may be planning on adding additional code to the print function later. You are correct that you could use document.write(listHTML) on it's own to achieve the same result.
