  8. Create a Cookie with JavaScript

    JavaScript can create cookies, read cookies, and delete cookies with the property document.cookie.
    With JavaScript, a cookie can be created like this:
    document.cookie="username=John Doe";
    You can also add an expiry date (in UTC or GMT time). By default, the cookie is deleted when the browser is closed:
    document.cookie="username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 GMT";
    With a path parameter, you can tell the browser what path the cookie belongs to. By default, the cookie belongs to the current page.
    document.cookie="username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 GMT; path=/";

    Read a Cookie with JavaScript

    With JavaScript, cookies can be read like this:
    var x = document.cookie;

    Notedocument.cookie will return all cookies in one string much like: cookie1=value; cookie2=value; cookie3=value;
  9. How a private variable implementation with javascript ? 
  10. How to create a simple object with javascript?

  11. Creating a Direct Instance

    The following example creates a new instance of an object, and adds four properties to it:

    Example

    person=new Object();
    person.firstname="John";
    person.lastname="Doe";
    person.age=50;
    person.eyecolor="blue";
  12. Alternative syntax (using object literals):

    Example

    person={firstname:"John",lastname:"Doe",age:50,eyecolor:"blue"};

  13. Using an Object Constructor

    The following example uses a function to construct the object:

    Example

    function person(firstname,lastname,age,eyecolor)
    {
    this.firstname=firstname;
    this.lastname=lastname;
    this.age=age;
    this.eyecolor=eyecolor;
    }

  14. Creating JavaScript Object Instances

    Once you have an object constructor, you can create new instances of the object like this:
    var myFather=new person("John","Doe",50,"blue");
    var myMother=new person("Sally","Rally",48,"green");
