Cognitive Complexity: the New Guide to Refactoring for Maintainable Code
Description:
Until now, there's been no good way to measure the understandability of a method. Cyclomatic Complexity was supposed to do that, but doesn't quite get it right. With the help of my colleagues at SonarSource (the company behind SonarQube) I've drafted Cognitive Complexity, which gives more accurate measures of control flow understandability.
In this talk, I'll explain the Cognitive Complexity methodology, show you how it applies to a number of code samples, and demonstrate how to use a method's Cognitive Complexity score as a guide to refactoring for simpler, more maintainable code.
