alt Hacker NewsMaybe this is misguided, but it feels a bit to me (comparing the ruby and js versions for example) that this is using the same code examples in both, and neither are really typical of the sorts of code people in either language community would actually write?
The problem: How do you have examples that are simple enough for those learning the refactoring tricks and techniques to quickly grok and be able to work on, and not overly complicated by the kinds of "real-world complexities" that do regularly appear in "real-world code."
I had the same "this isn't realistic!" complaint when studying the book, but the examples nonetheless helped me see, practice, and adopt the techniques so that I could immediately apply them to the complex production examples I needed to improve. YMMV... but as a former skeptic, "trust the process." Walk that path an work those examples for 5 days, then see how you feel. I was already pretty skilled, including in complex refactorings, and it still leveled me up.
