js object creation

Create Object

Literal way:

var myHonda = {color: "red", wheels: 4, engine: {cylinders: 4, size: 2.2}}

Is new Object()syntactic sugar, as the same.

The factory pattern:

function createCar(){    
  var oTemp = new Object();    
  oTemp.name = arguments[0];
  //直接给对象添加属性，每个对象都有直接的属性    
  oTemp.age = arguments[1];    
  oTemp.showName = function () {        
    alert(this.name);    
  };//每个对象都有一个 showName 方法版本    
  return oTemp;
};
var myHonda = createCar('honda', 5)

Just to new Object()pack a layer of skin, easy to mass production, and there is no essential difference, tentatively regarded as a way to create objects.

Constructor:

function Person(name, age, sex) {
  this.name = name;
  this.age = age;
  this.sex = sex;
  this.getName = function() {
    return this.name;
  };
}
var rand = new Person("Rand McKinnon", 33, "M");

The method getName constructor above, each instantiation of the function will create a new object also formed in the present case the eggs with no closure, it is a method of adding a constructor treated in the following manner, a method of adding to the subject when the factory mode should the following manner to avoid duplication object constructor

function Person(name, age, sex) {
  this.name = name;
  this.age = age;
  this.sex = sex;
  this.getName = getName
}
function getName() {
  return this.name;
};

The process of creating an object constructor and factory pattern is just about the same, equivalent hides create a new object and return the object of these two steps, in the constructor this point to New object is no different.
The biggest difference: constructor created object constructor property points to the constructor, the factory model point function Object(){...}.
Constructor prototype is equivalent to a plus chain ring, the prototype with its own constructor, factory pattern is a general function. Here I get a word of loopholes, constructor of the factory model to look at what is the point to which the first sentence of the new.
