CREATING OBJECTS
Define the function:

}
CREATING OBJECTS
To call object we use the keyword new. Exemple:
function myobject() {
this.containedValue = 0; this.othercontainedValue = 0; this.anothercontainedValue = 0;
}
var mything = new myobject();

Array: An array is a special variable, which can hold more than one value, at a time.
An array can be defined in three ways:

myCars[1]="Volvo"; myCars[2]="BMW";
– var myCars=new Array("Saab","Volvo","BMW"); – var myCars=["Saab","Volvo","BMW"];
