Ako v TypeScripte "nasimulovat" immutable triedy?

[heretik]

toto:

Kód: [Vybrat]

type Person(firstName, lastName) =
    member p.FirstName = firstName
    member p.LastName = lastName
    member p.FullName = sprintf "%s %s" firstName lastName
som sa v TypeScripte snažil vyjadriť nejako takto:

Kód: [Vybrat]

function Person(firstName: string, lastName: string) {

class Person {

readonly firstName = firstName;
readonly lastName = lastName;
get fullName() { return `${firstName} ${lastName}`; }

}

return Person;
}
lenže to neni úplne to isté nakolko to neni trieda ale "šablóna" tiredy nemôžem ju extendnúť... Ďediť môžem až výsledok funkcie.

A co takhle?

Kód: [Vybrat]

class Person {
  constructor(readonly firstName: string, readonly lastName: string) {}

  get fullName() {
    return `${this.firstName} ${this.lastName}`;
  }
}
