Using decorators you can wrap objects countless number of times since both target objects and decorators follow the same interface. The resulting object will get a stacking behavior of all wrappers.

在 TypeScript 中使用模式
Usage examples: The Decorator is pretty standard in TypeScript code, especially in code related to streams.
Identification: Decorator can be recognized by creation methods or constructor that accept objects of the same class or interface as a current class.
This example illustrates the structure of the Decorator design pattern. It focuses on answering these questions:
- What classes does it consist of?
- What roles do these classes play?
- In what way the elements of the pattern are related?
