// Task 1: Code a Person class
class person {
    constructor(name = "Tom", age = 20, energy = 100) {
        this.name = name;
        this.age = age;
        this.energy = energy;
    }
    sleep() {
        this.energy += 10;
        console.log('Energy is increasing, currently at:', this.energy)
    }
    doSomethingFun() {
        this.energy -= 10;
        console.log(console.log('Energy is decreasing, currently at:', this.energy))
    }   
}

// Task 2: Code a Worker class
class worker extends person {
    constructor(xp = 0, hourlywage = 10, name, age, energy) {
        super(name, age, energy);
        this.xp = xp;
        this.hourlywage = hourlywage;
    }
    goToWork() {
        xp += 10;
        console.log('Experience points is increasing, currently at:', this.xp)
    }
}
// Task 3: Code an intern object, run methods
function intern() {
    newIntern = new Worker(0, 10, "Bob", 21, 110);
    newIntern.goToWork();
    return  NewIntern;
}
intern();

// Task 4: Code a manager object, methods
