info: |
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.
