Last few months I have spent a lot of time doing code reviews. During the code review exercise I also pair with developers to refactor and improve the quality of their pull requests (PR). I care about two things in code reviews – correctness and understandability. In this post I will not focus on correctness (I might write a future post on this). Today, I want to focus on most important aspect of making code easier to understand – good names. Most of the time that I spend in the code review is coming up with the intention revealing names for classes, methods, interfaces, variables, packages, modules, and Microservices. I find most developers (irrespective of experience level) struggle to come up with good names.
