Thanks for the link, super interesting!

We have a super early form of runnable code, called "Surflets". More info here: https://github.com/deta/surf/blob/main/docs/SURFLETS.md

Basically you can supply input context and a runnable file will generate & run in your document. Useful for creating interactive charts or small applets.

Our philosophy is that if you want to update it, you should be able use your local code editor, not be stuck in Surf!

(we have work to do to make this solid)
