In the article, there’s an example where a graph object needs to be:

- converted to png

- converted into a promise of an array buffer

- awaited

- converted into a Uint8Array

- passed to Deno.jupyter.image

Just to display it in the notebook. In Python Jupyter, you can just return many types and the library/Jupyter will figure out how to render them.

A few lines of code isn’t much but in my experience for interactive coding to be productive you have to remove every bit of friction and boilerplate you can.
