Objects

• objects are created with the “new” keyword
• constructors for objects are simply functions
• the “this” keyword indicates the current instance of the object
• property variables can be defined within the function, but are not required to be, and can be added at any time

var dog = new Object();
dog.name = "fido";
dog.weight = 50;
dog.color = "Brown";

function animal(){
}
 
var dog = new animal();

function animal(name, weight, color){
	this.name = name;
	this.weight = weight;
	this.color = color;
}
 
var dog = new animal("fido", 50, "Brown");

var dog = {name:"fido", weight:50, color:"Brown};
