Design Mode-Prototype and prototype Some people may think that "pattern is used for mode ". As Insus. NET thinks, every master may have to do so before becoming a master. Walking, learning from an early age, till now, who is not walking to walk? Keep repeating ...... Many people do not share their own experiences, share their own processes, and share such things. It will not become less because of sharin

getName = function () {alert (4);}; This overwrites the function expression and makes a new assignment. Here return this, that is, execute this.getname (), which is called directly here, then this points to window. Output 1.(4), after the previous step, GetName () is covered, still output 1.5~7 questionsThe main constructor is to instantiate through new.(5), New (Foo.getname) (), GetName function is executed through the constructor, output 2Here is an issue with the return value of a constructo

The intent of the prototype pattern is to specify the type of object to create with the prototype instance, and to create a new object by copying the prototypes. Applicabilitywhen the class being instantiated is specified at run time, for example, by dynamic loading;To avoid creating a factory class level that is parallel to the product class hierarchy;When an instance of a class can have only one of sever

__PROTO__: This property is a property of an instance object, each of which has a __proto__ property that points to the prototype object (prototype) of the constructor that instantiates the instance.Proterty: This method is the property of the object. (it is said to be similar to an object's attr, such as in a DOM object)Prototype: Each constructor has a

PS One sentence: Eventually choose Csdn to organize the publication of the knowledge points of these years, the article parallel migration to CSDN. Because CSDN also support markdown grammar, Ah!OverviewTo understand prototype prototyping patterns, you must first understand shallow and deep replication in Java. In some places, replication is also called cloning. Java provides both of these cloning methods. Because the Clone () method is provided in Ja
