19,119 Pointsreturning a tring value from method
In the OOJ Challenge task the question is: Inside the stringGPA() method, convert the value of the gpa property to a string and return it.
I did:
class Student { constructor(gpa){ this.gpa = gpa; }
stringGPA() { this.gpa.toString(); } }
const student = new Student(3.9);
I get an error message that stringGPA is not returning a string
class Student {
constructor(gpa){
this.gpa = gpa;
}
stringGPA() {
(this.gpa).toString();
}
}
const student = new Student(3.9);
student.stringGPA();

And it doesn't cause an error, but you don't need the parentheses around "this.gpa".

1,011 Pointswhy we don't need to pass as an argument 'gpa' to the stringGPA() method?

231,268 PointsIt doesn't need an argument because it uses the "gpa" property that was stored in the object when it was created by the constructor.
