1. What is prototype?
The prototype attribute of the object in Javascript, which can return the reference of the Object Type prototype. This is a pretty straightforward explanation. To understand it, you must first correctly understand the concepts of object types and prototypes.As we mentioned above, the class of an object and the instance of an object are a
First, prototype (Prototype) modeBy giving a prototype object to indicate the type of object to be created, and then creating more homogeneous objects with the method of copying the prototype object. Prototype mode allows an object to create another customizable object witho
First, prototype and __proto__1, prototype (explicit prototype): Each function will have a property named prototype after it is created, which points to the prototype object of the function. It exists only in functions, such as the following example: function person (name)

Prototype ObjectEach JavaScript object has a prototype object, which is implemented differently under different interpreters. For example, under Firefox,Each object has a hidden __proto__ property, which is a reference to the prototype object.Prototype chainSince the prototype object itself is an object, it also has it
How to Understand JS prototype chain and JS prototype chain
Before talking about the prototype chain, we must first understand the relationship between user-defined functions and functions. What are the links between constructors, prototypes, and instances? In fact, all functions are Function instances. There is a prototype

Definition: Specify the kind of objects to create using a prototypical instance, and create new objects by copying this prototype.
The purpose of the prototype mode is to specify the type of the object to be created by givi
Prototype mode is the creation mode.Design intent: Use the prototype instance to specify the type of object to create and create a new object by copying the prototype.We use the class diagram of the example that builds the CV to illustrate the prototype pattern.Class Diagram:The prototype pattern is mainly used for obj
In javascript learning notes (8), we mainly learned how to create objects and add object attributes and methods when using javascript object-oriented programming. When using object-oriented programming, the inheritance relationships between objects are indispensable! Prototype is an important method to implement javascript inheritance!
Let's take a look at the following code:
The Code is as follows:
Function person (name, age ){This. name = name;Th
A detailed explanation of the principles of the Javascript prototype chain and a detailed explanation of the javascript prototype chain
This article analyzes the principles of the Javascript prototype chain. We will share this with you for your reference. The details are as follows:
I. JavaScript prototype chain

As mentioned in the article on JavaScript creation objects: One problem with creating objects with constructors is that the same method for different instances of the same constructor is not the same, so we use prototypes to extract the public properties and methods of the constructor for encapsulation. Achieve the purpose of having all instances shared.Next you'll learn more about JavaScript prototypes.First, JavaScript prototype mechanism 1, the rel
A good explanation of JavaScript inheritance, but slow to explain now. Don't say much nonsense, go straight to the chase.Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript object-oriented, such as what is not understood can refer to the "Object-oriented JS basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype mod

Prototype Pattern: Prototype Pattern and prototypepattern
I. Overview:
Use a prototype instance to specify the type of the object to be created and copy the prototype to create a new object. Simply put, an object is copied to generate a new object (Object cloning). The prototype

I. Understanding of javascript prototype
Many programming languages have the concept of classes. We can compare prototypes and classes to see the differences and similarities between them.
1. Class: class is the abstraction of a specific thing, so class is an abstract thing. In object-oriented mode, classes can be used to
The previous article tells the prototype concept of js, and here is a review of the definition of prototype:Prototype is a property of a function and is a prototype object of a Function. It is necessary to refer to the function, which should be remembered.but, It's strange, crossing, have you ever seen a JS code that references prototype like This:function func (
Ultimate explanation of JS prototype and prototype chain
1. Common objects and function objectsIn JavaScript, everything is an object! But there are also differences between objects. It can be divided into common objects and Function objects. Objects and functions are built-in Function objects of JS. The following is an example
Function f1 (){};Var f2 = function (){};Var f3 = new Function ('str', 'console.
Analysis of Principles and Examples of javascript prototype, prototype chain, and object replication (II)
PrototypePrototype is an important concept in JavaScript object-oriented features and is also a concept that everyone is too familiar. Because in most casesIn the object-oriented language of data, objects are class-based (such as Java and C ++), and objects are the results of class instantiation. InTher

Objects Created in JavaScript are created in many ways, such as factory mode, constructor mode, and prototype mode:
