Chapter 3 Naming rules Naming rules should be naming rules for variables, functions, and classes. I have heard of the "Hungary" Naming rules. The main idea is to add a prefix to the variable and function name to improve people's understanding of the program. For example, all character variables are prefixed with 'ch. If a variable starts with PPCH, it indicates that it is a pointer to a character pointer. T

argument. All two methods must be the first--this. For example Copy Code code as follows: var B = 10; function A (c) { alert (this.b); alert (c); } A (20); this = = Global, this.b = = 20 A.call ({b:20}, 30); this = = = {B:20}, this.b = = = 30 A.apply ({b:30}, [)]//This = = {B:30}, this.b = = = 40 Conclusion In this article, we discussed the characteristics of this keyword in ECMAScript (and they really are features, in contrast, say, with C + + or Java), th

easier to fix, and it's easy to know what the error is and where. Requirements analysis and testing time than writing code, the formation of software should pay more attention to demand analysis and testing, so as to reduce the software later appearing bugs, more meet the requirements of users, software can always be used and continue.Question: How do we begin to write unit tests when we don't write unit tests like this? What if I don't know if I wrote a unit test incorrectly?

Starting from this chapter, we will learn about triangle learning and apply it to animation technology in chapter 5.It will be exposed during the graphic technique. If you already know about triangle learning or want to learn about animation, you canSkip this part and come back to study when you encounter problems that you don't understand in the future. 90% of triangle learning we use needsMath. Sin and ma

This chapter parses script syntaxes that are essential in any language, including comments, variables, functions, and condition statements. The script format is as follows. /* Chapter 3 of game script design and development * // set the variable num to 5var. set (Num, 5); // conditional statement script to test if (@ num> 10); var. set (name, lufy); elseif (@ nu

used add-ons is pl/proxy. It has been around for years and provides excellent transparency and good extensibility. The idea behind Pl/proxy is basically to hide a table of server groups using a local virtual table. Pl/proxy will be discussed in depth in the 13th chapter, using the Pl/proxy extension. External Framework/Middleware You can also use external tools to replace dependent PostgreSQL. Some of the most widely used and well-known tools are: hi

Chapter 3 about DirectShow This section describes the overall architecture of DirectShow. There is a lot of knowledge in this chapter, and you don't need to master it all. Therefore, you can skip this chapter to see the topic "use DirectShow" that matches your program requirements. If you have some specific questions
