Clean Code Principles

Clean code isn't about following style rules until the linter goes quiet. It's about writing code that the next person, often a future version of the author, can read, change, and trust. The principles below are language-agnostic, but the examples are pure Java, and they all sit in the same online-store context used throughout the course. Sibling lessons cover coding standards (the formatting rules), Effective Java tips (the Java-specific design wisdom), common pitfalls, performance, and testing. This lesson is about the everyday craft that makes the rest of those decisions easier.
