- [Composite Pattern](https://banes-lab.com/records/architecture/composite-pattern.md): A design pattern that gives leaves and groups one interface, so a tree is traversed without checking which kind each node is.
- [Flyweight Pattern](https://banes-lab.com/records/architecture/flyweight-pattern.md): A design pattern that shares one copy of immutable intrinsic state among many objects, each keeping only its own extrinsic state.
