Vue.js 3 and Firebase for Beginners - Checking for Duplicate Basket Items

The video tutorial addresses the issue of adding duplicate items to a basket in a JavaScript application. It explains how to use the JavaScript find method to check if an item already exists in the basket by matching both the name and size of the pizza. If a match is found, the quantity of the existing item is increased instead of adding a new item. The tutorial includes testing the solution to ensure it works correctly.
