Adventures in Elm: Question your Principles • Jessica Kerr • YOW! 2016

Challenges, and unexpected freedoms. Elm is a purely functional language for the browser. It compiles to JavaScript -- after enforcing immutability, types, semantic versioning, and tight boundaries for user and server interactions. Working within these restrictions, I find my programming principles turned upside down. Small components? who needs them. Global state? no problem. New principles emerge instead: events, reproducibility, kindness in times of error. This session gives an overview of Elm, then focuses on the Elm Architecture: how it overturns what is essential in object-oriented and even backend functional programming.
