Sharing Mode = Singleton mode + factory mode + merging mode
Singleton mode:
Ensure that a class has only one instance and provides a global access point to it.
Structure:
Pay attention to the multi-threaded Singleton.

1. Differences and connections between the adapter mode and the Bridge Mode
The adapter mode and bridge mode both indirectly reference objects. Therefore, the system can be more flexible. in implementation, requests are sent from an interface other than itself to the referenced object.

This is a combination of my work in the actual project.Design patterns, in fac

Proxy ModeThe Proxy mode is A common design mode. It is mainly used to provide A 'agent' access to an object
In object-oriented programming, the most common approach is to create an object instance with a new operator, which is used to construct an object instance. In some cases, however, the new operator directly generates the object, causing some problems. For example, the creation of many types of objects requires a series of steps: You may need to calculate or get the initial settings of the object; Select which child object instance to generate; Or, you must generate some accessibility objects bef

In simple factory mode, I personally think it is to separate the client program from the class object. The user does not consider which method to call, I only need to tell you some of my features to

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

Scenario Description:
Assume that there is a User class (as shown below). The original design program uses SqlServer for Access. Now, Access is required due to changes in customer requirements.

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.
Factory mode
