: The instance method of JS must use the This keyword, and the class's methods usually do not use the This keyword, they refer to its parameter operation;The P222-based inheritance mechanism in the extended p223js of class 9.4 is dynamic: Objects inherit properties from other prototypes, and if the properties of the prototype change after the object is created, it also affects all instance objects that inherit the prototype, and we can augment the JS class by adding a new method to the prototype

the function that declares it and in any function nested within the body of the function. So in a function body, no matter where the variable is declared or even before it is declared, it can be used (without prompting for an error), but only after it has been declared and assigned, can it use the value assigned to it correctly. Therefore, in general, a good habit is to put the local variables to be declared in the function body at the top of the function body. var scope= "Global"; function f (

two chapters are very abstract and difficult to understand, and the code examples in the book are closely related to the previous content, because the knowledge points in the previous chapters are not thorough enough to understand the code.

distinguish between these, kinds of equality. One of the "identical" when talking about equality of references and the word "equal" when Talking about a distinct objects that has the same content. To test-nonidentical objects for equality, pass one of the them to the Equals () method of the other: All objects inherit a Equals () method (from Object), but the default implementa‐tion simply uses = = to test for identity of references, not equality of content.

Combining this article with the previous two articles, you should have a solid foundation for implementing your own aspect-oriented transformations in your Java application, either as a separate compilation step or at run time.To better understand the power of this approach, you can also analyze the JBoss Aspect oriented Programming Project (JBOSSAOP) built with Javassis.
