Specifies the function that creates an object.


object.constructor The required object argument is the name of an object or function.

The constructor property is a member of the prototype of every object that has a prototype. This includes all intrinsic JScript objects except the Global and Math objects. The constructor property contains a reference to the function that constructs instances of that particular object. For example:

x = new String("Hi");
if (x.constructor == String)
 // Do something (the condition will be true).


function MyFunc {
// Body of function.
y = new MyFunc;
if (y.constructor == MyFunc)
 // Do something (the condition will be true).
