Category: After learning about such a multi-mode model, many behavior patterns have also been designed during the learning process. What are the behavior patterns? One by one.

Design Patterns-understanding of appearance patterns Appearance mode: provides a consistent interface for a group of interfaces in the subsystem. This mode defines a high-level interface, making the subsystem easier to use. In the data room charging system, the appearance mode is used to remove the coupling between the U layer and the B layer. According to the pr

developers, never care about these behaviors. The code is as follows:JavaScript var address = (function// address module function(obj) { Address.refresh (obj); }); return { function(avatar) { console.log (' Refresh receipt address List ');} } ;}) ();Advantages and Disadvantages Supports simple broadcast communication and automatically notifies all subscribed objects; After page loading publishers can easily have a dynamic association wi

. the difference between equals and = = Earlier we saw that both the Clone object and the equals and = = of the original object return false, whether it is a shallow copy or a deep copy. So what is the relationship between equals and = =? For basic data types, = = compares their values. For non-primitive types of objects, = = comparison is their address in memory, such as the previous oldobject and newobject the same address, while the Equals method, if it does not overwrite the quilt class, it

The external interfaces of the system are provided by the appearance class. When a complex system needs to provide external interfaces, it needs to encapsulate the interfaces provided extern

Adapter mode1) Class of Adapter mode　　　2) The adapter mode of the object　　3) adapter mode for the interfaceThe adapter for the interface is this: sometimes we write an interface with multiple abstract methods, and when we write the implementation class of the interfaces, we must implement all the methods of the interface, which is obviously sometimes wasteful, because not all methods are needed, sometimes only some, here in order to solve this problem, We introduced an interface adapter patte

When a new type of observer appears. The code for the theme does not need to be changed.The subject does not care about anything else, just sends a notification to all objects that implement the Observer interface.The

of the Object.defineproperties or Object.defineproperty method type. It allows you to set properties such as enumerable, writable, or configurable. If you want to implement prototype mode yourself, instead of using object.create directly. You can use code like the following to achieve the above example:varVehicleprototype ={init:function(Carmodel) { This. Model =Carmodel; }, Getmodel:function() {Console.log (' Vehicle mould is: ' + This. Model); }};functionVehicle (model) {functionF () {}; F.pr
