Object Oriented Javascript

Object Constructor

function Cat(name) {
  this.name = name;
  this.talk = function() {
     alert( this.name + " say meeow!" )
  }
}

Creating Objects

• using constructor of defined object
  

  myCat = new Cat("Kuting");
  

• using new Object()
  

  person = new Object()
  person.name = "Bel"
  person.run = function() {
    this.state = "running"
    alert( this.name + " is running!" )
  }

• using literal notation
  

  person = {
     name : "Bel",
     siblings : ["Ana", "Marie"],
     run : function(){this.state = "running"; alert( this.name + " is running!" )}
  };

Prototyping - attaching a method to an object

Cat.prototype.changeName = function(name) {
   this.name = name;
}
