composition-over-inheritance

SKILL.md

Inheritance creates tight coupling and rigid hierarchies. Composition creates flexible, reusable components that can be mixed and matched.

Default to composition. Use inheritance only for true type hierarchies.

| Diamond problem | Duck needs Flying AND Swimming | | Tight coupling | Child knows parent internals | | Rigid hierarchy | Can't change parent without breaking children | | Forced inheritance | Gets methods it doesn't need | | Fragile base class | Parent changes break all children |

À utiliser lorsque vous êtes tenté d'utiliser l'héritage de classe. À utiliser lors de la création de hiérarchies de classes. À utiliser lorsque la sous-classe n'a besoin que d'un certain comportement parent. Source : yanko-belov/code-craft.
