19.5.1 The Error Constructor
|
|
|
|
...
|
|
The Error constructor is designed to be subclassable. It may be used as the
|
|
alue of an extends clause of a class definition. Subclass constructors that
|
|
intend to inherit the specified Error behaviour must include a super call to
|
|
the Error constructor to create and initialize subclass instances with a
|
|
[[ErrorData]] internal slot.
