Anyone can write code that works. The real skill is writing code that still makes sense a week later. Clean code isn’t about perfection—it’s about clarity.
You might write code once—but you (and others) will read it dozens of times.
That means readability beats cleverness every single time. Shortcuts, hacks, and overly compact logic may feel smart in the moment, but they slow everyone down later.
Write code like you're explaining it to someone else.
If you struggle to name a variable, you probably don’t understand the problem well enough.
Good names remove the need for comments.
Bad names create confusion that spreads across your entire codebase.
userData tells you nothing.authenticatedUserProfile tells you everything.
When a function starts doing too much, it becomes impossible to reason about.
Small, focused functions are easier to test, debug, and reuse. Large functions become black boxes no one wants to touch.
If your function needs scrolling, it needs splitting.
Comments should explain why, not what.
If your code needs a comment to explain what it’s doing, it’s probably not clear enough. Rewrite it instead of explaining it.
Clean code speaks for itself.
You don’t need perfect code—you need consistent code.
Follow patterns. Stick to conventions. Keep things predictable.
Because predictable code is easy to navigate—and easy to trust.
