First line of the example script on the home page seems off.

From this project's home page:

Certainly the first line in the red block is not intended?

Hello @sgbeal!

The code is actually correct. If you save the example snippet as an HTML file and open it in your browser you should see it works as expected. Though I can certainly understand your confusion. The reason that the createPdf function can be called prior to its definition in the code is due to function hoisting.
