It's refreshing to see a piece written by someone who's new to functional programming, discovering the beauty of types and pure functions for the first time.

I very much agree with the author; learning functional programming idioms have had a profound impact on my ability to model problems in code, regardless of the language I'm using.

I admire Elm so much for putting an emphasis on the user experience, recognizing that it has been one of the biggest blockers to making functional programming mainstream.
