print(listHTML) prints the document

Strange, but if I keep line 20 of the code print(listHTML) my computer goes to print this (on a printer). I've changed that line to document.write(listHTML) and everything goes fine. Is that because we no longer have the helpers.js file available to link it with index.html?

Hi Zeljko Porobija,

Line 20 calls the print function in playlist.js. Did you accidentaly remove it? :)


You can try this out in the browser console (ctrl+shift+i in chrome for windows).

Try typing in print(), this should open up a print window that wants to print out the page. Close it down.

Paste this into your browser console and press enter.

function print(message) {

Now try typing in print("Hello") instead and see what happens.

This is essentially what you did:


Does it make sense? :)

Wow, I commented that out (for the reason that escapes my mind). Thanks!
