I searched here and haven’t found any way

1. To easily assign a type to a class method (method2: Method isn’t a class method in pure sense it’s an “instance” (own property) method).
2. When you override a parent method there’s no easy way to infer type of the child method, so I used Parameters<> (and I have extremely complex parameter list (with typed callbacks, etc)).
3. There’s satisfies keyword but I don’t understand how it could be applied to this case

type Method = (n: number) => number;

class A{
  method(n: number){
    return n;
  }
  method2: Method = n => n;
}

class B extends A {
  method(...[n]: Parameters<A['method']>){
    return n;
  }
}

Any help how to make optimal DRY (without repeating a long method list in an interface and again in classes) typing would be appreciated.
