I love refactoring. Nothing satisfies me more than untangling spaghetti code to reveal its underlying logic in a clear, intuitive way. I’ve learned that refactoring requires diligence. In my younger and more reckless days, I would rush into a legacy codebase and tear apart the code without any concern for controlled changes. Inevitably, days or weeks later, I would discover that I broke the code by removing a subtle piece that seemed irrelevant but was, in fact, critical for an obscure scenario.
