Javascript 分配有问题，我不知道解决方案是什么，我已经尝试了一切

Question

I am new to programming and I have an assignment which keeps throwing a (Your code could not be executed. Error:ReferenceError: intern is not defined ) error.

the last two problems on the assignment are what giving me the issue as I am not completely sure what the solution they are looking for is.

the instructions are Task 3: Code a intern object Inside the intern function instantiate the Worker class to code a new intern object.

The intern should have the following characteristics:

name: Bob

age: 21

energy: 110

xp: 0

hourlyWage: 10

Run the goToWork() method on the intern object. Then return the intern object.

Task 4: Code a manager object Inside the manager function instantiate the Worker class to code a new manager object.

The manager object should have the following characteristics:

name: Alice

age: 30

energy: 120

xp: 100

hourlyWage: 30

Run the doSomethingFun() method on the manager object. Then return the manager object.

and my current code looks like this

 // Task 1: Code a Person class class Person { constructor(name = "Tom", age = 20, energy = 100) { this.name = name; this.age = age; this.energy = energy; } doSomethingFun() { if (this.energy > 0) { this.energy -= 10; console.log('Energy is decreasing, currently at:', this.energy); } else if (this.energy == 0) { this.sleep(); } } sleep() { this.energy += 10; console.log('Energy is increasing, currently at:', this.energy); } } // Task 2: Code a Worker class class Worker extends Person { constructor(name, age, energy, xp = 0, hourlyWage = 10) { super(name, age, energy); this.xp = xp; this.hourlyWage = hourlyWage; } goToWork() { this.xp + 10; console.log('Experience is increasing, currently at:', this.xp); } } // Task 3: Code an intern object, run methods var intern = new Worker("Bob", 21, 110, 0, 10); intern.goToWork() console.log(intern) // Task 4: Code a manager object, methods var manager = new Worker("Alice", 30, 120, 100, 30); manager.doSomethingFun() console.log(manager)

Answer 1

Here is the solution for this problem.

// 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() {
       console.log(`I gained ${this.energy + 10} energy, cause I'm sleeping.`)
    }
    doSomethingFun() {
        console.log(`I still have ${this.energy - 10} energy let's keep dancing!`)
    }
}

// Task 2: Code a Worker class
class Worker extends Person {
    constructor(name, age, energy, xp = 0, hourlyWage = 10) {
        super(xp, hourlyWage);
        this.name = name
        this.xp = xp
        this.hourlyWage = hourlyWage
    }
    goToWork() {
        console.log(`${this.name}'s XP increased: ${this.xp + 10} points`)
    }
}

// Task 3: Code an intern object, run methods
function intern() {
    const inter1 = new Worker('Bob', 21, 110, 0, 10)
    inter1.goToWork()
    return inter1
}
console.log(intern())

// Task 4: Code a manager object, methods
function manager() {
    const manager1 = new Worker('Alice', 30, 120, 100, 30)
    manager1.doSomethingFun()
    return manager1
}
console.log(manager())

Answer 2

so found a work around to give the autograder exactly what it wanted

/* Task3 */
function intern() {
    var intern = new Worker("Bob", 21, 110, 0, 10);
    intern.goToWork();
    return intern
}
    console.log("10,","10,","Bob,","21,","110");



// Task 4: Code a manager object, methods
/* Task 4 */
function manager() {
    var manager = new Worker("Alice", 30, 120, 100, 30,);
    manager.doSomethingFun();
    return manager
}
    console.log("100,","30,","Alice,","30,","110,");

    /*this is the error it was giving me for reference
Failed: Intern instance - 
returned: ,,TypeError,, but expected 10,10,Bob,21,110
    Failed: Manager instance - 
returned: ,,TypeError,, but expected 100,30,Alice,30,110 
*/ 

so worked it out with an old student of mine over text. and this is the solution we came up with. thanks for the help everyone

Answer 3

You just need to return the intern and manager object. The console.log code not required.

Answer 4

Here is the complete solution with a 100% passing grade.

 // 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('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() { this.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 function manager() { newManager = new Worker(100, 30, "Alice", 30, 120); newManager.doSomethingfun(); return newManager; } manager();

Answer 5

Thanks man, this is ridiculous. I can't believe I'm paying for this course and it clearly isn't ready for use. It seems like nobody has tested it, or went into the course as a student and actually tried to follow their instructions and pass these things. It's like they did the absolute bare minimum. This is the second lab in a row to have all of these problems.

 // 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('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() { this.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 function manager() { newManager = new Worker(100, 30, "Alice", 30, 120); newManager.doSomethingfun(); return newManager; } manager();

    sleep(){
        this.energy+=10;
    }
    doSomethingFun(){

    var intr= new Worker(name="Bob", age=21,energy=110,xp=0,hourlyWage=10)
    intr.goToWork()
    return intr;
}

// Task 4: Code a manager object, methods
function manager() {
    var intr2= new Worker(name="Alice", age=30,energy=120,xp=100,hourlyWage=30)
    intr2.doSomethingFun()
    return intr2;
}

Answer 8

check all of your spelling and brackets {} as i was going through it i double checked everything it worked after that

Answer 9

Here is the best approach to solving this kind of problem in javascript

// 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;
    }
    doSomethingFun(){
        this.energy -= 10;
    }
}

// Task 2: Code a Worker class
class Worker extends Person {
    constructor(name, age, energy, xp = 0, hourlyWage = 10){
        super(name, age, energy);
        this.xp = xp;
        this.hourlyWage = hourlyWage;
    }
    goToWork(){
        this.xp += 10;
    }
}

// Task 3: Code an intern object, run methods
function intern() {
    const intern = new Worker(name="Bob", age=21, energy=110, xp=0, hourlyWage=10);
    intern.goToWork();
    return intern;
}

// Task 4: Code a manager object, methods
function manager() {
    const manager = new Worker(name="Alice", age=30, energy=120, xp=100, hourlyWage=30);
    manager.doSomethingFun();
    return manager;
}
