Tengo un constructor padre como este:

 let list = []; class Pictures { constructor(price, title) { this.price = price; this.title = title; list.push(this) } updatePrice(price_increase) { this.price = this.price * price_increase / 100 + this.price return this.price } }

También tengo dos clases secundarias que heredan de la clase Pictures(Parent)

 class Photograph extends Pictures { constructor(photographer, camera, aperture, contrast, price, title) { super(price, title); this.price = price; this.title = this.title; this.photographer = photographer; this.camera = camera; this.aperture = aperture; this.contrast = contrast; } alterContrast(new_contrast) { this.contrast = new_contrast; } toString() { return `Photographer: ${this.photographer}, Camera: ${this.camera}, Aperture: ${this.aperture}, Contrast: ${this.contrast}`; } }

Y:

 class Painting extends Pictures { constructor(artist, type, owner, title, price) { super(price, title); this.price = price; this.title = title; this.artist = artist; this.type = type; this.owner = owner; } printProvenance() { } toString() { return `Artist: ${this.artist}, Type: ${this.type}, Owner: ${this.owner}`; } }

Y estas son las instancias de las clases.

 let photo_one = new Photograph('Kyle', 'Nikon', 32, 21, 30, 'Sunset') let photo_two = new Photograph("Maya", "Sony XPR", 100, 23, 100.00, "Festival of Color");

Empujé todas las instancias a la matriz de "lista" en el constructor principal. ¿Es posible recorrer la matriz y usar el método updatePrice en la clase Pictures para actualizar el valor del precio de todos los objetos?
