25.1.1.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();

The first line creates a new instance of Object and stores it in the variable oObject;

The second line creates a new instance of String and stores it in the variable oStringObject.

The parentheses aren't required when the constructor doesn't require arguments, so these two lines could be rewritten as follows:

var oObject = new Object;
var oStringObject = new String;
