I am have been reading material on JavaScript and there are two ways of accessing the title of the page:

1. The window.title property
2. The document.title property

But when applying, the second only works. I am unable to understand why there are two titles and why both of them don't work.

• There aren't. window.title is not a universal property, whereas document.title is. Fire up you're browser's console, and type "window.t" and see what it tries to autoplete with. There will be no "title" in that list. – Mike 'Pomax' Kamermans Commented Jun 19, 2013 at 1:44

window.document.title is correct.

window.title is incorrect, because the window object doesn't have a title property (all the properties of window are down the left side, you'll see title isn't there).
