framer prototype

I. Object: Normal Object Function objectTwo. Constructor features: 1. A new instantiation is required, and the This object is used internally to point to the instance object 2 that is about to be generated. Uppercase letters, used to distinguish common functionsfunction Person (name) { the name=name}var person1=New person (' Xiaohong ') )var person2=New person (' Lili ')Person1.constructor=person constructor points to constructors, person's built-in properties Person.prototype (function objec

The intent of the prototype model is: By giving a prototype object to indicate the type of object you want to create, you can then create more objects of the same type with the method of copying the prototype object. This pattern has been implemented in the Java class Library, so long as you define a class that implements the Cloneable interface, objects create

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

If you want to understand the internal relationship between function and object, you must introduce another two concepts dominant prototype and stealth [[prototype]] Concepts1. Prototype: Each function object has a display prototype property that represents the prototype of

Although the prototype pattern is a pattern of creation, it has nothing to do with the engineering model, and the idea of the pattern is to copy and clone an object as a prototype, and create a new object similar to the original object. This summary will be explained by the copy of the object. In Java, the Copy object is implemented through clone (), and a prototype
