Courses Plus Student 7,229 PointsWhy am I getting error: "student.stringGPA is not a function"?
Inside the stringGPA() method, convert the value of the gpa property to a string and return it.
class Student {
constructor(gpa, stringGPA){
this.gpa = gpa;
this.stringGPA = stringGPA;
}
stringGPA(){
return toString('gpa');
}
}
const student = new Student(3.9);

11,166 Pointsyou should call the toString() method on the property:-
class Student {
constructor(gpa){
this.gpa = gpa;
}
stringGPA(){
return (this.gpa).toString();
}
}
const student = new Student(3.9);

And "tosString" is not a plain function, but it is a method you can attach to a numeric variable using the dot notation.
I'll bet you can get it now without an explicit spoiler.

class Student {
constructor(gpa, stringGPA){
this.gpa = gpa;
this.stringGPA = stringGPA;
}
stringGPA(){
return this.gpa.toString();
}
}
const student = new Student(3.9);
