javascript getters and setters

/*Getter functions are meant to simply return (get) the value of an object's 
private variable to the user without the user directly accessing the private 
variable.*/
/*Setter functions are meant to modify (set) the value of an object's private 
variable based on the value passed into the setter function. This change could
involve calculations, or even overwriting the previous value completely.*/
class Book {
  constructor(author) {
    this._author = author;
  }
  // getter
  get writer() {
    return this._author;
  }
  // setter
  set writer(updatedAuthor) {
    this._author = updatedAuthor;
  }
}
const novel = new Book('anonymous');
console.log(novel.writer);  // anonymous
novel.writer = 'newAuthor';
console.log(novel.writer);  // newAuthor
