JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

Posted by Caleb Newell

Inside the major() setter method, set the student's major to a backing property "_major".....

Inside the major() setter method, set the student's major to a backing property "_major". If the student's level is Junior or Senior, the value of the backing property should be equal to the parameter passed to the setter method. If the student is only a Freshman or Sophomore, set the "_major" backing property equal to 'None'.

I have no Idea what I am doing wrong. Can anyone help? 😕

creating_setters.js 
class Student {
    constructor(gpa, credits){
        this.gpa = gpa;
        this.credits = credits;
    }

    stringGPA() {
        return this.gpa.toString();
    }

    get level() {
        if (this.credits > 90 ) {
            return 'Senior';
        } else if (this.credits > 60) {
            return 'Junior';
        } else if (this.credits > 30) {
            return 'Sophomore';
        } else {
            return 'Freshman';
        }

    }

      get level() {
        if (this.credits > 90 ) {
            return 'Senior';
        } else if (this.credits > 60) {
            return 'Junior';
        } else if (this.credits > 30) {
            return 'Sophomore';
        } else {
            return 'Freshman';
        }
    }

    get major() {
        if (level === 'Senior' || level === 'Junior') {
            major = this._major;
        } else {
            major = 'none';
        }    
    }

    set major(major) {
        this._major = major;
    }
}

var student = new Student(3.9, 60);

Hi Caleb Newell

Your logic is perfect. You just have to implement this logic in the setter method.

Like this:

 this._major = major;
if ( this.level === 'Senior' || this.level === 'Junior') {
     return this._major;
    } else {
      this._major = 'none';
      return this._major; 
    }
}
