JavaScript Object-Oriented JavaScript Getters and Setters Creating Setter Methods

Posted by Kaleshe Alleyne-Vassel

Setter method is returning the wrong value for the major property, don't know how to get the right one

I'm so confused. I don't understand how get and set work properly. The if statement in the setter is being completely ignored, I tried swapping it to the getter section to no avail and now I have no idea what to do.

I'm finding this getter and setter section very confusing, and can't think of how it can be used in the real world

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

var student = new Student(3.9, 60);

This challenge doesn't ask you to create a getter. The setter has two syntax issues (and a misspelling):

  • logic operators only work when combining complete comparisons
  • the assignment operator is "=", a "===" is a comparison operator
  • the challenge asks for the default setting to be "None" (with capital "N")
      if (this.level === 'Junior' || this.level === 'Senior') {  // use COMPLETE comparisons
            this._major = major;
          } else {
            this._major = 'None';                                // = instead of ===, and "None"

I added the getter because I wasn't sure if that was why it wasn't working. But I didn't notice that I hadn't done the || thing correctly. Thanks, it just takes someone else looking at something to point out a few things.
