Elm in Action is that way. Over the course of the book you build a photo sharing application from scratch. Each chapter uses new "feature requests" from a fictional manager as a way to introduce and teach new Elm concepts. https:

Well said! It would be wonderful if all programing language comparisons were this clear and this calm.

Yep! I'm writing this from Elm in the Spring, the 2nd of 4 dedicated Elm conferences in 2019. JS/TS continue to dwarf everything else, but it's possible that Elm is the most widely used JS alternative at this point. (Hard to
