Refactoring for Readability in Ruby: a Showcase - DEV Community

My personal solution to this: write the code as readable as possible from the very beginning. The key skill to do this is an ability to recognize levels of abstraction in your code. Once properly recognized, they can be isolated from each other, which drastically reduces the mental effort required to understand what's going on in the code. There is a so-called "Single Level of Abstraction" (SLA) principle, popularized by Uncle Bob in his book Clean Code, that is all about that.
