NodeJS: Cohesion and Coupling | Peter McKee


Peter McKee

What makes good software? What's the difference between well written code and code that's not? There are two foundational principles that are at the core of well written code - cohesion and coupling. Well written code is loosely coupled and highly cohesive. Whether you write object-oriented, procedural or functional code, it must follow these two principles to be able to be easily reasoned about and maintained. In this talk we'll discuss cohesion and coupling and take a look at poorly written code and how to think about and refactor it to be loosely coupled and highly cohesive.
