Answer 1

class Worker {
    constructor(id, _name, _age) {
        this.id = id;
        let name = _name;
        let age = _age;
        this.show = function () {
            console.log(this.id + ' ' + name + ' ' + age);
        };
        Object.defineProperty(this, 'WName', {
            get: function() {
                return name;
            },
            set: function(value) {
                name = value;
            }
        });
    }
}
   
const worker = new Worker(2345, 'Tom', 54);
 
worker.show();
 
console.log(worker.id);
 
console.log(worker.name);
 
console.log(worker.WName);
 
worker.WName = 'Rey';
 
worker.show();
 
 
     
/*
run:
   
2345 Tom 54
2345
undefined
Tom
2345 Rey 54
 
*/
