Script not working

Can anyone tell me why this isn't working?

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);

That code works for me, how have you added it to your html document? What isn't working for you?

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Musical Playlist</title> <link rel="stylesheet" href="css/styles.css"> </head> <body> <h1>My Music Playlist</h1> <script src="js/playlist.js"></script> </body> </html>

HTML looks fine. When I hit preview out of Workspaces, I only get "My Music Playlist" on top with nothing else under it.

Are you able to snapshot your workspace so it's easier to see what's going on? It's in the top right corner when you have the workspace open.

I just forked your workspace and it works fine for me with all six items displayed. Have you tried opening the preview URL in a private browsing window or another web browser? Might just be something funky going on with cached data.

Yea the same thing was happening to me. My code seldom run from the workspace, but that same code always works when I download the project files and run them in my own editor and browser window.
