What is it important to add the JavaScript code?

I implemented the below JavaScript code, and I realized it wasn't populating the list. Then I took a look at my HTML and I didn't have the <li> the list order inside HTML. Once I added the <li> it showed. I guess my question is, what's the point in having the JavaScript code there if it is already showing through the HTML? ~~~ JavaScript Code

var playList = [ 'I Did It My Way', 'Respect', 'Imagine', 'Born to Run', 'Louie Louie', 'Maybellene' ];

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

function printList ( list ) { var listHTML = '<ol>'; for ( var i = 0, i < list.length; i+=1) { listHTML += '<li>' + list[i] + '</li>'; } listHTML += '</ol>'; print(listHTML); } printList(playList);

Hi Kyle, In this case it's more of an exercise in using an array and "marrying" it with HTML than I feel it's a practical application to use on a website, but I'm a beginner myself, perhaps others have more input.
