I think we might be doing it wrong. We should have functions that do things to the DOM, functions that tell us about the DOM, but not both at the same time." I'm dealing with that very same issue right now! It's a relatively small project, but I haven't separated my code well enough, and debugging has been proving to be difficult... “It’s weird how difficult its been to test and debug our Javascript.

I have some trouble to understand above long statement. Please divide the statement two or more statements. Thanks.
