Help I'm not sure how to implement the conditionals in this

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

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 major(){
    return this._major;
  }
  */
  set major(major){
    this._major = major;

  }
}

var student = new Student(3.9, 60);

There's some good examples of "if" conditionals in the code for the "level" getter. While they test the value of the credits to determine what to return, you'll be testing the level to determine what to store into _major.

Give it a shot, and if you still have trouble show the code you have tried.
