Elm - Friendly functional programming for the Web


Intro
====
- I'm just learning
- Evan Czaplicki, Harvard, programming for the Web doesn't have to be painful
- Ideas from academia
- Rocks the FP community boat by making ideas approachable


What is Elm?
====
- Compiled to JS
- Reliable, 0 runtime exceptions, OOM, recursion
- Stateless functions, strongly typed, no mutable values at all
- Very fast. About 50% faster HTML rendering than React.js


DEMO REPL
- Strongly-typed values
- Functional application, curried by default
- Pipeline operator, composing functions
- Record types, how to update them, type aliases
- Union-types, pattern matching


The Elm Architecture
====
- The Elm Architecture is a simple pattern for creating webapps. The core idea is that your code is built around a Model of your application state, a way to update your model, and a way to view your model.
- Redux is inspired by Elm


DEMO UI
- Fibonnaci list

Why not Elm?
====
- Current version 0.18 < 1.0
- Fast development with breaking changes, although the upgrade is usually not too much effort
