Creating objectsFirst type: Object-basedvar New = ' My Name '=function() { returnthis. Name;}Second: The object literal way (a more clear Lookup object contains the properties and methods)var person = { ' My name ', +, function() { return This . Name;} }
Objects can be created using th
The first three methods are essentially the same, with the following memory:JS the first way to create an object (create a new instance of an object):var person = new Object ();Person.n
This section describes how to create your own objects, how to create constructor methods, and how to create public, private, privileged, and static members.
How to create your own objects: Let's talk about the following three points:
1. Let's start with the simplest example: var myobject =

Using constructors to create objects
A constructor is a function called to instantiate and initialize a particular type of object . You can invoke a constructor by using the new keyword. A new example of
/*** Construct a copy of a new object based on the parameters of the specified method and return it* @ Param OBJ original object* @ Return new object* @ Throws nosuchmethodexception* @ Throws invocationtargetexception* @ Throws illegalaccessexception* @ Throws instantiatione
variables or functions are separated by semicolons.
(5) The function must be written in braces of function.
Example:
VaR data = {};
Data. Prototype. Name = "Vicky ";
Data. Prototype. Age = 20;
Data. Prototype. Eat = function (){
Alert ('I wanna eat meat ');
};
Data. Prototype. Sleep = function (){
Alert ('I wanna sleep ');
};

This method uses the prototype JavaScript component library.
