+
+> Our first episode is all about functions! We talk a bit about what makes functions special, contrasting them with the way we usually write code, and have some exploratory discussions about operators and composition.

+### Side Effects
+
+> Side effects: can’t live with ’em; can’t write a program without ’em. Let’s explore a few kinds of side effects we encounter every day, why they make code difficult to reason about and test, and how we can control them without losing composition.

+### UIKit Styling with Functions
+
+> We bring tools from previous episodes down to earth and apply them to an everyday task: UIKit styling. Plain functions unlock worlds of composability and reusability in styling of UI components. Have we finally solved the styling problem?
