-
๐๐น๐ฒ๐ ๐ถ๐ฏ๐ถ๐น๐ถ๐๐: Composition allows for easier combining and altering of behaviours without affecting other parts of the system.
-
๐๐ผ๐ผ๐๐ฒ ๐๐ผ๐๐ฝ๐น๐ถ๐ป๐ด: Composition reduces component dependency, making systems more maintainable.

๐ข๐๐ฒ๐ฟ๐ฐ๐ผ๐บ๐ฒ๐ ๐ฆ๐ถ๐ป๐ด๐น๐ฒ ๐๐ป๐ต๐ฒ๐ฟ๐ถ๐๐ฎ๐ป๐ฐ๐ฒ: While many languages only support inheriting from one class, composition lets an object combine multiple components.
-
๐๐น๐ฒ๐ฎ๐ฟ ๐ฅ๐ฒ๐น๐ฎ๐๐ถ๐ผ๐ป๐๐ต๐ถ๐ฝ๐: Composition often leads to clearer HAS-A relationships (e.g., a ๐ฒ๐๐ has an ๐ด๐๐๐๐๐) as opposed to the IS-A relationships of Inheritance.
-
๐ฅ๐ฒ๐๐๐ฎ๐ฏ๐ถ๐น๐ถ๐๐: Objects can be reused in various contexts without creating subclass hierarchies.

๐๐๐ผ๐ถ๐ฑ๐ ๐๐ฟ๐ฎ๐ด๐ถ๐น๐ฒ ๐๐ฎ๐๐ฒ ๐๐น๐ฎ๐๐ ๐ฃ๐ฟ๐ผ๐ฏ๐น๐ฒ๐บ: Changes in a base class might unintentionally affect subclasses. Composition mitigates this issue.
-
๐๐๐ป๐ฎ๐บ๐ถ๐ฐ ๐๐ฒ๐ต๐ฎ๐๐ถ๐ผ๐ฟ: Composition allows changing of operations at runtime by switching out components.
-
๐๐ป๐ฐ๐ฎ๐ฝ๐๐๐น๐ฎ๐๐ถ๐ผ๐ป: Composition can better hide the internal details of components.
-
๐ฅ๐ฒ๐ฎ๐ฑ๐ฎ๐ฏ๐ถ๐น๐ถ๐๐: Overusing Inheritance can cloud code's origin and purpose. Composition tends to be more explicit.
-
๐๐ฒ๐๐ฒ๐ฟ ๐ฆ๐ถ๐ฑ๐ฒ ๐๐ณ๐ณ๐ฒ๐ฐ๐๐: Composition reduces unexpected behaviours by containing them within distinct objects.
While Inheritance models "IS-A" relationships, Composition's ๐๐น๐ฒ๐ ๐ถ๐ฏ๐ถ๐น๐ถ๐๐, ๐๐น๐ฎ๐ฟ๐ถ๐๐, and ๐ ๐ฎ๐ถ๐ป๐๐ฎ๐ถ๐ป๐ฎ๐ฏ๐ถ๐น๐ถ๐๐ often make it a more suitable choice for modelling "HAS-A" relationships.
