Unable to transform data types

Currently, I am studying the JavaScript for automation session at WWDC. Here is an example taken from slide 99 that I am working on. On a fresh installation of Yosemite, I encountered an error on line 3.

Safari = Application('Safari')
doc = Safari.document[0]
url = doc.url() // -> this is where the issue occurs
doc.url = 'http://apple.com'

Answer №1

There is a small error on the slide. The correction needed is in the second line:

doc = Chrome.documents[0]
                     ^

Change documents (plural) instead of using document.
