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

help, I dont know what I'm doing wrong

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

    stringGPA() {
        return this.gpa.toString();
    }
  get level(){
    let output ="";
    if(this.credits => 90){ output + 'Senior';

    }else if(this.credits <= 61 ){ output +'Junior';

    }
    }else if (this.credits <= 31 ){ output + 'sophomore';

    }else( output += freshman
  )
  return output;


  }
}

const student = new Student(3.9);

A few observations.

  1. You invoke a new Student object, yet you are only passing one of the required values. You need the GPA and the Credits in order to successfully invoke a new Student object.
  2. Your get level method contains a space, which won't work. You'll need either get_level() or getLevel()
  3. After you invoke the new Student object, you need to call the method on the object to return the level. For example:
const student = new Student(3.9, 64);
student.get_level();
  1. Your class method has an arrow function embedded in it which is incorrect. => is attempting to read as an arrow or anonymous function.
  2. You forget the += code in your assignment of the level, instead only using + operator.

Here is the revised code, which when provided with the gpa and credits, correctly returns the level:

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

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

  get_level() {
    let output ="";
    if (this.credits <= 90) {  //removed arrow operator here
        output += 'Senior'; //remember to use += instead of +
    } else if (this.credits <= 61 ) { 
        output += 'Junior';
    } else if (this.credits <= 31 ) { 
        output += 'sophomore';
    } else { 
        output += 'freshman'; 
    }
    return output;}
}

const student = new Student(3.9, 94);
student.get_level();
>>> 'freshman' // this is clearly wrong, so work on the number logic for calculating level.
