Answer 1

type CompanyWorker = {
    id: number;
    name: string;
    age: number;
    show_details?: () => string;
    show_string?: () => string;
};

const workers: CompanyWorker[] = [
    {
        id: 82927,
        name: "Axel",
        age: 37,
        show_details() {
            return `${this.id} ${this.name} ${this.age}`;
        }
    },
    {
        id: 98272,
        name: "Blaze",
        age: 41,
        show_details() {
            return `${this.id} ${this.name} ${this.age}`;
        }
    },
    {
        id: 76362,
        name: "Isla",
        age: 31,
        show_string() {
            return "Just a string";
        }
    }
];

console.log(workers[0].show_details?.());
console.log(workers[1].show_details?.());
console.log(workers[2].show_string?.());

  
  
/*
run:
  
"82927 Axel 37" 
"98272 Blaze 41" 
"Just a string" 
  
*/
