JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

Inside the major() setter method, set the student's major to a backing property "major". Im not understanding ?

i cant seem to understand what is required and how to excute,its a new concept...still digesting it. 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 {
    set major(major){}
    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';
        }
    }
}

var student = new Student(3.9, 60);

You might want to review the Setters video, particularly from about a minute and a half in, where it discusses the concept of a "backing property" and shows an example of creating one.

Show the setter method code you've written so far by using the video example as a model.
