Description
Returns or sets the descriptive string associated with a specific error.
Syntax
object.description [= stringexpression]

The description property syntax has these parts:

Part Description
object Any instance of an Error object.
stringexpression A string expression containing a description of the error.

Remarks
The description property contains the error message string associated with a specific error. Use the value contained in this property to alert a user to an error that you can't or don't want to handle.

The following example illustrates the use of the description property:

try {
  x = y                              // Cause an error.
}
catch(var e {                        // Create local variable e.
  document.write(e)                  // Prints "[object Error]".
  document.write((e.number & 0xFFFF))// Prints 5009.
  document.write(e.description)      // Prints "'y' is undefined".
}
