Composition over inheritance: Drawbacks, Example & Benefits

In object-oriented programming, composition over inheritance (sometimes composition with forwarding or composite reuse) is a common design pattern that tries to achieve code reuse without requiring inheritance. Instead of having two child classes inherit functionality from a common parent, composition simulates inheritance by having the children include…
