This walks you through clean code principles, SOLID design patterns, and practical code review checklists with side-by-side examples of what not to do and how to fix it. You get meaningful naming conventions, function design, when comments actually help versus when they're noise, and concrete implementations of each SOLID principle in TypeScript. The code review section includes a checklist covering correctness, design, and readability. It's most useful when you're refactoring legacy code, onboarding new developers who need to learn your standards, or during PR reviews when you need to articulate why something should change beyond just "this feels wrong."
