Next is Decorator Design Pattern
The decorator enables us to add functionality to an existing object without needing to create a new inheritance chain or update the prototype. The idea is to add functionality to items based on need instead of adding them to the object from the get-go. This can become very useful when you have multiple objects with partially shared functionality.
