Any help please?
Thank you so much!
class Media {
constructor(title) {
this._title = title;
this._isCheckedOut = false;
this._ratings = [];
}
get title() {
return this._title;
}
get isCheckedOut() {
return this._isCheckedOut;
}
get ratings() {
return this._ratings;
}
set isCheckedOut(value) {
this._isCheckedOut = value;
}
toggleCheckOutStatus() {
this.isCheckedOut = !this.isCheckedOut;
}
getAverageRating() {
let ratingsSum = this.ratings.reduce((accumulator, rating) => accumulator + rating);
return ratingsSum / this.ratings.lenght;
}
addRating(value) {
this.ratings.push(value);
}
}
class Book extends Media {

const historyOfEverything = new Book ('Bill Bryson', 'A Short History of Nearly Everything', 544);
historyOfEverything.toggleCheckOutStatus();
console.log(historyOfEverything.isCheckOut);
