Challenge 1 / 1

In Turbo Drive, how can we tell when a page is a preview or a freshly downloaded page?

document.body.hasAttribute('data-turbo-preview');

document.querySelector('body').hasAttribute('data-turbo-preview');

document.documentElement.hasAttribute('data-turbo-preview');

There is no way of differenciating between a preview and a real page in Turbo.
