Decorator mode:
In the process of object-oriented design and development, you may often encounter the following situations. We need to add new responsibilities for a defined class, in this case, we will define a new class to inherit the custom class, and solve this situation through inheritance will bring about system complexity, because the depth of inheritance will become very deep. The decorator provides a method to add responsibilities to the clas

Command mode
The responsibility chain forwards requests along the class chain, while the command mode only forwards requests to a specific object. In command mode, a request for a specific operation is encapsulated into an object and a well-known public interface is provided to the object

After reading so many explanations about the factory model in the Java factory model, I still feel that this article is easy to understand and share with you.I. IntroductionTen years ago, there was a *** user who had three cars in his house, Benz, BMW, Audi, and hired a driver to drive for him. However, *** it is always strange to take a taxi: the Benz car was followed by the driver and said, "drive a Benz car !", When he got on BMW, he said, "kaibao carriage !", Get on with Audi and say, "Drive

What is Object oriented? Object oriented is an idea! (nonsense).
Object-oriented can treat key modules in a program as objects, and modules have attributes and methods. In this way, if we encapsulate some attributes and methods, it will be very convenient to use in the future and avoid tedious duplication of work. Next, we will explain the object-oriented implementation in JS.

Objective:
Before we've talked about decorator patterns, wrapping objects up and giving them new responsibilities, we also wrap objects in this chapter, just to make them look like they're not something else. This allows the interface of the class to be converted into the desired interface in the design to imp
