In software development, the Decorator Pattern is a structural design pattern that improves the flexibility and scalability of the code by dynamically adding new functions to objects. Unlike inheritance, the Decorator Pattern achieves functional enhancement by combining objects, and multiple decorative functions can be selectively superimposed at runtime. This article will introduce the concept of the Decorator Pattern in detail, the difference between it and other similar patterns, the problems it solves, its implementation in Golang, and the precautions in practical applications. …
