Declaration and Instantiation
Objects are created by using the new keyword followed by the name of the class.
var oObject = new Object(); var oStringObject = new String();
When there are no remaining references to an object, the object is said to be dereferenced.
It is possible to forcibly dereference objects by setting all its references equal to null.
var oObject = new Object; oObject = null;
