also be executed on newly created objects by using the Apply () and Call () methods (in the future)1, pass the parameter: compared to the prototype chain, borrowing a constructor has a great advantage, you can pass the parameters to the copy type constructor in the sub-type constructor function.2. The problem of borrowing constructors: there is no way to avoid problems with constructor patterns-methods are defined in constructors, so functions cannot be reused. Also, in the case of super-type p
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, this is a very good
myself figured out, spent a long time. But then I saw the book "Thinking in Java", which read these concepts.
The third step is to learn the characteristics of Java object-oriented programming language
such as inheritance, constructors, abstract classes, interfaces, polymorphism of methods, overloads, Overrides, Java
Object with attributes and methods. This is what everyone has heard. Object-oriented features include closed, inherited, and polymorphism. Today, I want to summarize what I just learned. I just wrote down the tip of the iceberg and hope it can be improved.
I believe everyone is familiar with Object Inheritance. You can

child class instances might be affected by a property that has a reference type value on the prototype object (because the parent class's properties are all copied over on the subclass, the Parent property is overwritten). But in this way, subclasses extend inconvenient when we want to extend the parent class, such as when the parent class becomes a function Sup (a, B). So, here's an improved notation (the idea I've been told by an interviewer):Sup.a
: Note The Serialversionuid inconsistency throws a serialized run-time exception.11. The "forced" construction method prohibits any business logic from being added, and if there is initialization logic, put it in the Init method.12. The "force" Pojo class must write the ToString method. When using the IDE's tools:source> generate ToString, if you inherit another Pojo class, be careful to add super.tostring to the front. Description: When the method execution throws an exception, you can directly

I found that learning from JSP and then turning to Java is a good process for me. An expert in programming said, "The object-oriented technology has been reduced.ProgramEntry threshold ", I think this sentence can be put into the network technology, changed to" JSP technology reduces the entry threshold for Java programs ". Using JSP technology, you can useCodeFe

, JavaScript does not have a specific syntax or implement inheritance and polymorphism at the language level. However, this does not prevent us from using these features. This is because JavaScript is a flexible language, and it is quite flexible enough that none of these things are provided, or, more precisely, things that are not clearly indicated, can be implemented and used! So, can you say that JavaScript is object-based rather than
