JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

Bummer: Your setter method is returning the wrong value for the major property.

What am I doing wrong here?

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;
        if(this._major == "Junior")  {
            this._major = "Junior";
        }
        if(this._major == "Senior")  {
            this._major = "Senior";
        }
        if(this._major == "Sophomore" || this._major == "Freshman") {
            this._major = "None"; 
        }

    }
}

var student = new Student(3.9, 60);

Hey Nikhil J , nice work. It looks like you are close on this one. But the setter method is supposed the check if the this.level === 'senior' or this.level === 'junior', etc. And then the backing property gets set to the parameter being passed to the setter. Unless that param is freshman or sophomore. Then the backing property gets set to 'none'.

Also, you don't need to set the backing property initially before the if statements. And you should avoid using the loose equality operator unless you're absolutely sure that's what you want because otherwise it can lead to unexpected results. So when comparing values, you should pretty much always be using the strict equality operator: ===.

Thanks, Robert, that cleared it for me.
