Many JavaScript-oriented programming methods are popular on the market, many of which are problematic. Here's a summary of the most correct JavaScript object-oriented programming patterns. For class Special inheriting from class Common inheriting from class Super, the creation of a Special object, in detail, should go through the following steps. 1 Determining the inheritance Relationship 1.1 Read Special's

decryption, compression and decompression, and so on (that is, the computer can recognize things to convert adults can recognize things (such as pictures, sounds, etc.). 7. Application layer: Mainly some terminal applications, such as FTP (a variety of file downloads), the WEB (ie browsing), QQ and so on (it can be understood as we can see on the computer screen things.) is the terminal application). Network applications: Network programming, IO str

Speaking of interface-oriented programming. I heard a blur.Problem: Now there are interface A and the B class that inherits a interface, thenA s=new B;What does that mean???Then you can adjust the method implemented in class B with the method of a s.print.And the teacher said that interface-oriented programming is to reduce the coupling degree of the program (what is the meaning of the coupling). More secur

Interface-oriented representation subclasses are implementation interfaces or abstract classes, and implementation-oriented representations inherit common classes. Obviously the former coupling is relatively low, because the modification code is relatively low, because the interface and abstract class itself some methods do not do things, but subclasses to achieve. Design principles: Identify the parts of the application that may need to change, and separate them from the ones that don't change.

, the desktop IP set to 192.168.127.222, and the IP of the notebook is 192.168.137.1, the two are not a network segment at all. After the desktop was changed to 137, the two moxa IP was changed to 192.168.137.252, 192.168.137.201. Successful implementation of the most basic communication. 2, the client's socket in the settings must use the server's IP and port ... Socket programming in the server, the port needs to indicate that IP with inaddr_any (Le

worry about DDD.2. specification introduces the idea of FP DevelopmentDdd was not technically poor, and then it proposed the specification closure. Clearly, people will know that closure comes from FP. Let's take a look at the basic features of functional programming first:1. Closure Calculation and high-level functions.A function itself is a first class object, and a closure acts as a function a

Man invented the programming language in order to control the machine. Computers are becoming more powerful, and programming languages are constantly being innovated. So I boldly believe that the meaning of programming language will be beyond the control of the machine, it may be a starting point of civilization-robot civilization. To better envision the

following DDD, because the support for the interface cannot be simple and persistent, and there is also a great deal of trouble for the transformation of thinking; 2.1 Two design misunderstandings for Interface Programming First of all, I think the first misunderstanding is the interface dependency problem. The interface dependency is not a small problem, and there are strict requirements for dependencies

Almost all software schools (including my school) use C language (hereinafter referred to as C) to teach C syntax and usage. This means: 1. c is the first programming language most students have learned; 2. When most students are involved in programming at school, they initially focus on programming languages. So there are two questions: 1. Is it appropriate to u

So where are their differences? Pr
