Abstract:

What do you get when you combine strict functional programming with heavy user interaction? 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.
