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".
}
