That’s a mighty lot of words, to say “functional core, imperative shell”.

Maybe I’m being glib, but damn, a whole article, and boatloads of fancy new terminology, just to re-state what the author succinctly landed on in the _first_ paragraph:

> Create your application to work without either a UI or a database so you can <do a bunch of nice stuff and make your life easier>”.
