I want to use Salary Type for salaries class variable. how can i do it ? please help me

export class Employee {

  id: string = "";
  birth_date: string = "";
  emp_no: string = "";
  first_name: string = "";

  salary: string = "";
  rom_date: string = "";
  to_date: string = "";


}

CodePudding user response：

there are two errors: salaries: Salary = null; and this.salaries = new Salary();

in many cases you don't need a class but you can use a Type or an interface, i.e.

export interface Employee {
    id?: string;
    birth_date?: string;
    emp_no?: string;
    first_name?: string;
    last_name?: string;
    gender?: string;
    hire_date?: string;
    salaries?: Salary;
}

export interface Salary {
    id?: string;
    emp_no?: string;
    salary?: string;
    rom_date?: string;
    to_date?: string;
}
