TypeScript-da OOP klasslari meros olishi

TypeScript-da klasslarning meros olishi odatiy tarzda amalga oshiriladi, xuddi saf JavaScript-dagidek.

Keling, sinab ko'raylik. Faraz qilaylik, bizda quyidagi klass mavjud:

typescriptclass User {
  name: string;
  
  constructor(name: string) {
    this.name = name;
  }
}

Keling, ushbu klassdan meros olaylik:

typescriptclass Student extends User {
  course: number;
  
  constructor(name: string, course: number) {
    super(name);
    this.course = course;
  }
}
