The getter method should return the level of a student, based on how many credits (this.credits) they have.

Why is this not working? :(

class Student { constructor(gpa, credits){ this.gpa = gpa; this.credits = credits; }

stringGPA() {
    return this.gpa.toString();
}

get level() { if (credits>90) { return 'Senior'; } if else (credits =< 89 && credits > 60) { return 'Junior'; } if else (credits=<60 && credits >= 31) { //60 or fewer credits, but more than 30 (>= 31), they are a 'Sophomore'. return 'Sophmore'; } else (credits=<30) { return 'Freshman'; } //30 or fewer credits, they are a 'Freshman'. } }

const student = new Student(3.9);

creating_getters.js
class Student {
    constructor(gpa, credits){
        this.gpa = gpa;
        this.credits = credits;
    }

    stringGPA() {
        return this.gpa.toString();
    }

  get level() {
    if (credits>90) {
      return 'Senior';
    } if else (credits =< 89 && credits > 60) {
      return 'Junior';
    } if else (credits=<60 && credits >= 31) {
      //60 or fewer credits, but more than 30 (>= 31), they are a 'Sophomore'.
      return 'Sophmore';
    } else (credits=<30) {
      return 'Freshman';
    }
      //30 or fewer credits, they are a 'Freshman'.
  }
}

const student = new Student(3.9);

There are a few issues:

  • the instance variable "credits" needs to have the "self." prefix
  • the operator for "less than or equal" is "<=" (instead of "=>")
  • the keywords for "else if" are written out of order
  • a plain "else" does not take a conditional expression
  • the correct spelling of "Sophomore" should have 3 o's (instead of "Sophmore")
  • the credit value of exactly 90 is not being correctly identified by the conditional expression
