Full Stack JavaScript Techdegree Student 13,897 Pointsquick question on what would be the better method here.
in the exercise the constructor for the patron class specifies that it should be
class Patron{
constructor(name,email){
this.name = name;
this.email = email;
this.currentBook = null;
}
checkout(){};
returnBook(){};
};
would it not make more sense to have an argument which can pass in the current book but if none is give it instead defaults to null like this?
class Patron{
constructor(name,email,currentBook= null){
this.name = name;
this.email = email;
this.currentBook = currentBook;
}
checkout(){};
returnBook(){};
};

If patrons are added as they receive their borrowing privileges in a new library, then by definition they would never already have a "currentbook" to register.
But if this system was replacing an older one, then yes, it would be handy when creating records for existing patrons to add their current book as the record is created.
