We introduce a project we're going to work on over a few episodes. To get familiar with the code, we build a new feature using the app's view-state driven approach.
We use the reactive array type from episodes #67 and #69 to back a table view. This allows us to correctly animate changes in the underlying data, even with filter and sort transformations applied.
We refactor our reducer-based project from episode #62 to use The Elm Architecture. Instead of interacting with UIKit directly, we build a virtual view hierarchy and let our Elm framework do the rest.
