How do I make the gpa value return as a string?

What do I need to add to my code to convert the value for gpa into a string value? I can't think of anything and I don't think the previous video ever went over it.

adding_methods.js
class Student {
    constructor(gpa){
        this.gpa = gpa;
    }

    stringGPA(){
        console.log(this.gpa);
    }
}

const student = new Student('3.9');

student.stringGPA;

The toString() method is best for this

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

You'll also want to remove the ticks around 3.9 in the Student declaration
