Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Reusable solution templates for recurring problems in software design. The classic 23 patterns are divided into: - Creational (e.g., Singleton, Factory) - Structural (e.g., Adapter, Decorator) - Behavioral (e.g., Observer, Strategy). Scaffolding role: using pattern language to improve design communication efficiency. Design patterns are the crystallization of experience; naming patterns allows teams to express complex design intentions with a single word, and also helps novices quickly learn mature solutions.
