How to define a property as a class that extends another class?

Question

typescript

Please tell me how in TS how to define any class that extends let's say some kind of conditional RegExp ??
Like this:

class T extends RegExp {...}
class E extends RegExp {...}

interface ChtotoTam {
   f: любой класс который extends RegExp
}

Interested in this case f in the interface ChtotoTam

It is clear that can be defined as

interface ChtotoTam {
   f: T | E
}

But I would like this interface to automatically expand somehow if we have other classes that are extended by RegExp

Answer 1

Well, put it there RegExp. Any class that extends it will do.

interface ChtotoTam {
   f: RegExp
}
