Observable provides an environment for live JavaScript coding with some additional bells and whistles that, so far, seem to be making my life a bit easier.
Present-me thinks future-me is probably going to spend a lot of time coding on Observable, and embedding the notebooks on this website. This is my first attempt. (View the HTML source to see how ridiculously easy it was to do the embedding).
The notebook itself is my introduction to coding on Observable.
Some features may not display as intended, and you will not be able to interact with the code.
To view the actual notebook on Observable (which you should), you can follow
