Basic object-oriented JS explanation, factory mode, constructor mode, prototype mode, hybrid mode, dynamic prototype modeWhat Is Object-Oriented? Object-oriented is an idea! (Nonsense ). Object-oriented can regard all key modules in the program as objects, and the module has attributes and methods. In this way, if we encapsulate some attributes and methods, it will be very convenient to use in the future an

Comparison of the six most common prototype file formats and six prototype file formats Internet product partners will not be unfamiliar with the term "prototype. Like "User Experience", it is often spoken by various people. Prototype is a way for users to experience products, exchange design ideas, and display compl

I. Common objects and Function objectsIn JavaScript, everything is Object! But the object is also different. is divided into ordinary objects and function objects, object, function is JS comes with the functions of the object. The following examples illustrateFunction F1 () {};var F2 = function () {};var F3 = new Function (' str ', ' Console.log (str) ');var O3 = new F1 ();var O1 = {};var O2 =new Object ();Console.log (typeof Object); functionConsole.log (typeof Function); functionConsole.log (t

Prototype mode (PROTOTYPE)Defined:Prototype mode: Specifies the kind of object created with the prototype instance, and creates a new object by copying the prototypes. The copied instance is called a prototype, and the prototype is customizable.Prototype pattern is also a cr

Javascript prototype and prototype chainAs we all know, JavaScript does not contain the traditional class inheritance model, but uses the prototype model. The code implementation is probably like copying the code function Student (name) {this. name = name;} var Kimy = new Student ("Kimy"); Student. prototype. say = fun

After the process of creating the object and the new method is clear, it is much easier to understand the concept of the prototype.The purpose of the prototype exists in order to be more memory-efficient inheritance.I think the main thing in the prototype is to figure out what these 4 concepts are, what the explicit prototypes point to, what the implicit prototypes point to, what the constructor points to,

The prototype attribute can be considered a big difference between JavaScript and other object-oriented languages.In short, prototype is "a method of adding methods to objects of a class," and using the prototype property, you can dynamically add properties and methods to the class to achieve the effect of "inheritance" in JavaScript .The object that is construct

Agreed to explain the JavaScript inheritance, but delayed to now explain. No more nonsense, go straight to the point. Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript-oriented objects, such as what you do not understand can refer to the object-oriented JS Basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype m

Introduction to prototype in JavaScript, and javascript prototype Inheritance in JavaScript is completed through prototype chain: each object has another object as its prototype, and the object inherits the property from this prototype ). For each object, you can use the fol

Prototype and closure are the difficulties of JS language, this article mainly talk about prototypes.Each of these methods has a property that is prototypeEach object has a property that is _proto_Once a prototype attribute or prototype method is defined, all objects instantiated through the constructor inherit these prototyp
