JavaScript a new way to create objects-object.create ()

What is 1.object.create ()?

Object.create (Proto [, Propertiesobject]) is a new way of creating objects in E5, the first parameter is the prototype to inherit, if not a child function, you can pass a null, the second argument is the object's property descriptor, This parameter is optional.

For example:

function Car (desc) {    THIS.DESC = desc;    This.color = "Red";} Car.prototype = {    getinfo:function () {      return ' A ' + this.color + ' + This.desc + '. ';    }};/ /instantiate object using the constructor Functionvar car =  object.create (car.prototype); car.color = "Blue"; alert ( Car.getinfo ());

The result is: A blue undefined.
