JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

backing property

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'.

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';
        }
    }

    set major(major) {
      this._major = major;   
      if (this.credits > 90 || this.credits > 60 ) {
        return major;
      }else if(this.credits > 30 || this.credits < 30) {
        return 'none';
      }
    }

}

var student = new Student(3.9, 60);

You need to check your conditions against the level() get method.

e.g. if (this.level)

Make sure you then correctly set the value of the backing property, which has the underscore _ preceding it and rhe string matches what is in the question. So it's "None", not "none". That last bit might sound a bit picky but code challenges are like that, I'm afraid. :)

the problem is that your setting the major value even before the if statement, set the major property according the if statement, and you don't have to return anything, the if statement should SET the major according the conditions
