I didn't know I was doing literate programming when I started using Observable. It's changed the way I code in a huge way. The code isn't tucked away, so it's like repos in VS Code are hidden caverns, and Observable collections are canyons in the light of the Sun. They can remain private, of course, but the barriers to sharing are negligible compared to the common Git-centered workflows.

Codesandbox and Google Colab come close but they still feel like tanks. I can code something up on my phone with Observable while waiting in line at the DMV...
