The Quest Begins (The "Why")
I still remember the first time I opened a legacy repository and saw a function called handleStuff(). Inside, there were 200 lines of nested loops, a few magic numbers, and a comment that said “TODO: refactor this someday”. I spent an entire afternoon tracing why a user’s profile picture wasn’t showing up, only to discover that the bug lived three functions deep inside handleStuff(). Every time I tried to fix something, I felt like I was wandering through a maze blindfolded—pulling one lever and watching a completely unrelated wall crumble.
That experience taught me a hard truth: if you can’t tell what a piece of code does just by reading its name, you’re already losing the battle. The dragon I was trying to slay wasn’t a complex algorithm; it was the fog of vague naming and overloaded responsibilities that made every change a gamble.
The Revelation (The Insight)
The treasure I uncovered wasn’t a new framework or a fancy library. It was a simple, almost obvious principle: give every function a name that reveals its intention, and keep it focused on a single job. In other words, treat each function like a member of a fellowship—each with a clear role, a distinct purpose, and the trust that they’ll do exactly what they say they will.
