Anyone can write code a computer can understand, but professional developers write code humans can understand. This session discusses best practices for writing code in a style that’s easy to create, maintain and understand. We have a lofty goal: programming style as documentation. We’ll discuss concrete methods to get you there and give you a vocabulary for pragmatically evaluating code quality. Various refactoring techniques, code smells, anti-patterns, and rules of thumb are discussed including fail fast, return early, separation of concerns, arrow code, magic numbers, the boy scout rule, being “stringly typed”, DRY, the stepdown rule, table-driven methods, the importance of staying native, techniques for finding subtle redundancy, reinventing the square wheel, when to create a method, doing comments right, horizontal and vertical density, and simple design patterns. Part of this session involves refactoring a confusing and ugly chunk of code into something beautiful, easy to read and maintain. While examples are in C#, coders in any language should be able to follow along and apply the principles discussed.
