error: "student.stringGPA is not a function" keeps popping up when trying to convert a number to a string

class Student {
    constructor(gpa, stringGPA){
        this.gpa = gpa;
        this.stringGPA = stringGPA;
    }
  stringGPA(){
    return this.gpa.stringify();

  }
}

const student = new Student(3.9);

I'm trying to convert the gpa variable into a string inside the stringGPA method, however the error "student.stringGPA is not a function" error keeps popping up. Any help or feedback on this is much appreciated.

adding_methods.js
class Student {
    constructor(gpa, stringGPA){
        this.gpa = gpa;
        this.stringGPA = stringGPA;
    }
  stringGPA(){
    return this.gpa.stringify();

  }
}

const student = new Student(3.9);

To convert a number to a string in Javascript, you could use this.gpa.toString() or JSON.stringify(this.gpa).

The issue was actually with this.stringGPA - it shouldn't have been defined like it was above (even though the test let me pass with it in the module before)
