But JScript .NET supports a more structured exception: the Error object. An Error object is thrown by the system whenever there is a run-time error. You can throw your own Error objects, and thus keep all exceptions of the Error type. You create Error objects with the Error constructor:

  function Error([number : Number [, description : String ]])

• number is a numeric value assigned to the exception. It is optional.
• description is a brief string that describes the exception. It is optional.

You can create a new Error object, populate it, and throw it, all in the same statement. For example:

  throw new Error(35,"null object, call your vendor");
