Convert a value to string!

I try to compleat the method inside this class but I get an error as the string() is not defined. I am using this method to convert the value of gpa ( which is a number) to a string but I get that error. Would you please help me :)

class Student {
    constructor(gpa){
        this.gpa = gpa;
    }
    stringGPA (){
     string(this.gpa);
  }
}

There's no common function named "string", but numbers have a method called .toString() that could be handy.

Also, this method needs to return the converted value.

Thanks for the answer. I found that method on the link below !!! But later I found the toString().
