21.2.3 The RegExp Constructor
|
|
|
|
|
|
|

...

|
|
|
|
|
|
|
|
The RegExp constructor is designed to be subclassable. It may be used as the
|
|
|
|
|
value of an extends clause of a class definition. Subclass constructors that
|
|
|
|
|
intend to inherit the specified RegExp behaviour must include a super call to
|
|
|
|
|
the RegExp constructor to create and initialize subclass instances with the
|
|
|
|
|
necessary internal slots.
