It's a real pain. I work with lots of "data science" types who are often trying to concurrently learn JavaScript and d3 - often with JS as their first or second programming language. It's difficult enough for an experienced programmer coming back to d3 after a few versions to pick out what's d3 vs. what's Observable - and very difficult to help a relative newbie through the process of turning what's shown in an Observable notebook into something that can run in an ordinary web page.
