How do I create an Object?

Martin Honnen,

There are different ways of doing that, the simpliest a call of
  new Object();
This creates an empty object to which you then can add properties e.g.
  var person1 = new Object();
  person1.name = 'James Kibo Parry';
  person2.home = 'http://www.kibo.com';
Starting with JavaScript1.2 you can also write Object literals (like 
you can write string literal e.g. 'string' or number literals e.g. 2):
  var person1 = 
    {name: 'James Kibo Parry', home: 'http://www.kibo.com' };
so an object literal is just a list of name: value pairs enclosed in 
curly brackets.
Suppose you want to store the data of many different persons all 
sharing the same properties so
  var person2 = new Object();
  person2.name = 'Nathan Wallace';
  person2.home = 'http://www.faqts.com';
etc. That task can be faciliated by defining your own object 
constructor for these class/type of person objects:
  function Person (name, home) {
    this.name = name;
    this.home = home;
  }
which you then use as follows
  var person1 = 
    new Person ('James Kibo Parry', 'http://www.kibo.com');
  var person2 =
    new Person ('Nathan Wallace', 'http://www.faqts.com');
