Anti-Pattern Driven

Start from common anti-patterns to understand why they fail, and how design patterns can improve them. Learn practical design through real-world code examples.

Focus on the Structure

Instead of memorizing pattern names and jargon, aim to explain "why the structure works" in your own words. Focus on the essence of design and develop structural intuition.

Refactoring by Choice

For each anti-pattern, multiple design pattern-based solutions are introduced. Learn to compare and choose patterns depending on the situation.
