PHP design pattern prototype mode, design pattern prototype
Prototype patterns are similar to engineering patterns, and are used to create objects.
Unlike the implementation of the engineering pattern, the prototype pattern is to create a good one prototype object and then
Primary roles in prototype mode

As we all know, JavaScript does not contain the traditional class inheritance model, but uses the prototype model. Code implementation is like this.

This article , referring to Http://www.blogjava.net/heavensay/archive/2013/10/20/405440.html's article, makes a brief summary of its contents, and forms a few simple conclusions. It makes it easier for readers to remember the relationship between prototype, __proto__, Object, and function. Conclusion 1:Object.prototype is just an ordinary object, it is the top of the JS prototype chain. (typeof object.prot

Prototype design is getting more and more attention, and its benefits do not need to be described here. From mobile Internet to traditional internet, prototype design will be involved.

Creating object objects directlyvar New Object (); var = {};stu.name= "Zhangsan"="stu"function() { alert ( "My name Zhang San"); }You can also use the Stu as a module, the module has a number of objects, the following example for a simple shopping cart system module!Shoppingcar.carinfo = function (obj) {Shoppingcar.carinfo . Carnumber = Obj.carnumber;.....}//Shopping Cart ObjectShoppingcar.orderinfo = function (obj) {Shoppongcar.orderinfo. ordernumber = obj.ordernumber;...}//Order ObjectCall
1. Object.create1>. Definition: Create an object that can specify a prototype object and which may contain optional custom attributes;2> object.create (proto [, properties]); Optional, to configure the properties of the new object;1. Proto: To create a prototype of a new object, it must be, nullable; This proto should have been created [new over], or object. prototype
We use the prototype property to provide a set of basic functions for the object's class. And a new instance of the object "inherits" the action given to the object's prototype. But how exactly is this prototype implemented and managed?
For a description of the object's prototype property, the JScript manual says: All
7.6 prototype mode Summary
Prototype is a method for quickly creating a large number of identical or similar objects. It is widely used in software development. Many software products provide copy (CTRL + C) and paste (CTRL + V) the operation is a typical application of the prototype mode. The following briefly summarizes the effects and applicability of the mode

Recently I learned nothing about what I think, and the progress is not obvious. So I occasionally look at the prototype source code and take notes for analysis.
I remember that when I used to look at jquery's source code, I searched the internet and analyzed a bunch of source code. However, most of them can only be regarded as comments. I am a beginner like me.
So now, jquery's source code only looks at the first few hundred lines. Select
