When I was a younger developer, I thought I knew how to make code better by, as the kids would say today, following vibes. Much later, a coworker gave me a copy of Martin Fowler’s Refactoring. I regret how long I put off reading it. Even later, I read Sandi Metz’s 99 Bottles of OOP and learned just how safe refactoring could be. Fearless refactoring is a skill that must be learned, and it is almost a superpower!
