For this lesson, let's take a look at the concept and usage of the final keyword. What is the final keyword? Final Chinese translates as "ultimate", "final". The final keyword modification before declaring a class means that the function will not be overloaded in any subclass, inheriting, that is, the final decorated class will no longer have subclasses. Prior to the course we said 4 kinds of keywords, public, private, protected, static, respectively, is common, private, protected, static. Usag

This article mainly introduces the advanced features of javascript object-oriented programming, and detailed the creation, access, deletion, object type, extension, and so on of javascript objects in the form of examples, for more

ObjectiveToday's JavaScript is a great way to rely on a wide range of applications. Web programmers have become accustomed to using a variety of excellent JavaScript frameworks to quickly develop WEB applications, ignoring the learning and deep understanding of native JavaScript. So, often the case is that many of the programmers who have done it for many years a

Recently, I was looking at the JavaScript advanced programming design (the third edition). The object-oriented chapter has more than 20 pages, and I went back and forth for three or five times. The results of each reading were different. The first time I went over it, I was confused, as a result, when I went to bed at night, I found a lot of problems and I couldn

Despite the differences between object-oriented JavaScript and other languages, and this has caused some controversy, there is no doubt that JavaScript has powerful Object-Oriented Programming capabilities. This article first intr

This article mainly introduces the concepts related to JavaScript object-oriented programming, such as classes, objects, attributes, methods, and other object-oriented terms, and explains the use of various terms with examples, th

NEW: string equality comparisons in JavaScript The application of the image object is quite extensive, it appears in the desktop programming very early, the application is more mature, like c++,java,c# etc. And in the Web programming this piece, appear much later, so that the current web development is difficult, of course, there are many technologies involved in web development reasons. In recent years,

The last two sections talk about JavaScript object-oriented namespaces and JavaScript-oriented JavaScript classes, so you can look at the above and continue to look down. In fact, it is very simple, less talk, read the following

method, or the new instance will have an error. This is because the subclass does not have its own this object, but instead inherits the parent class's this object and then processes it. If you do not call the Super method, the subclass will not get the This object.2. In the normal method of a subclass, because super points to the prototype
