I am experiencing an issue where my code is not iterating over the data in my

The issue I'm facing with the code below is that it only displays the quantity of the first item, rather than all items in my shopping cart.

import {ShoppingCartItem} from './shopping-cart-item';

export class ShoppingCart {
  constructor(public items: ShoppingCartItem[]) {}

  get totalItemsCount() {
    let count = 0;
    for (const productId in this.items) {
      if (this.items.hasOwnProperty(productId)) {
        count += this.items[productId].quantity;
        return count;
      }
    }
  }

}

Answer №1

To improve efficiency, modify the function by moving the return statement outside of the loop:

  get totalItemsCount() {
    let count = 0;
    for (const productId in this.items) {
      if (this.items.hasOwnProperty(productId)) {
        count += this.items[productId].quantity;        
      }
    }
    
    return count;
  }
