# Two things are important to note: 
#
# 1) The code is fugly, because it was a JavaScript/iPad experiment. 
#    I know that it is ugly, so pretty please don't comment on that part.
# 2) I tried to use as many CoffeeScript features as possible,
#    including but not limited to list comprehensions,
#    heredocs, destructuring assignment and also the "do" operator
#
# I welcome comments about stuff that is not CoffeeScripty enough, or what I should
# write differently.

Focus

A Focus is a way to work with particular parts of a large chunk of data. On the most basic level, it lets you get and set fields of a record in a simple and composable way. This means you could avoid writing special record update syntax and use something that composes much more elegantly.

This API is inspired by the concept of Bidirectional Lenses as described by Nate Foster and seen in a modified form in Haskell as "lenses" and in ClojureScript as "cursors". My personal opinions and understanding comes from this talk by Simon Peyton Jones, discussions with @seliopou, and a basic understanding of Nate Foster's PhD thesis on bidirectional lenses. I chose the name "Focus" for this outline because it is sort of like a lens that only lets you see in one direction.

Here's the pseudocode that describes the basic API:

Architecture in Elm

This document is a collection of concepts and strategies to make large Elm projects modular and extensible.

We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp. You will probably merge a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:

1. There is a single source of truth. Traditional approaches force you to write a decent amount of custom and error prone code to synchronize state between many different stateful components. (The state of this widget needs to be synced with the application state, which needs to be synced with some other widget, etc.) By placing all of your state in one location, you eliminate an entire class of bugs in which two components get into inconsistent states. We also think yo
