design patterns as another tool to add to your developer toolbox. We will start this talk by introducing the taxonomy of design patterns at a high level, how to read a UML diagram (as a quick refresher) Surely a solution must exist to this common problem ○ So there has to be a better way... 20 Introducing--Design Patterns!Design Patterns 21Design Pattern (1/2) ● A common repeatable solution for But what if we also need to modify other behaviors? ■ e.g. The sf::Text.draw() function? 59 Introducing--Structural Design Patterns (Our second category)Structural Design Pattern Focus on using inheritance

written within one or more test declarations can be used to ensure behavior meets expectations: introducing_zig_test.zig 1 const std = @import("std"); 2 3 test "expect addOne adds one to 41" { 4 5 return number + 1; 15 } Shell 1 $ zig test introducing_zig_test.zig 2 1/1 test "expect addOne adds one to 41"...

nat : Type | zero : nat | succ : nat → nat The first line announces to the world that we are introducing a new type called nat, intended to represent the natural numbers. The second and third line de- we can factor it out and put it next to the function’s name, as a parameter, before the colon introducing the type of the function (excluding the parameter m): def power2 (m : N) : N → N | nat.zero := Notice that the recursive call to power2 does not take m as argument. In the entire def block introducing power2, m is fixed as the first argument. Outside the block, power2 is a (curried) binary function
