Coding challenge: cartified!

Hey JavaScript talents, here at namshi.com, we are looking for you! Submit this coding challenge to alex.nadalin@namshi.com and we'll get back to you as soon as possible!

Your task is to implement a basic shopping cart for a website, following these basic rules:

• the cart needs to be implemented as an AngularJS service
• the cart should be retrieved from the localStorage, where it's stored under the key cart
• every time an action is performed on the cart, it should be persisted on the localStorage
• the cart should only know about item IDs and their quantity

  echo sprintf("hello %s\n", $name);
}

async function run() {
  $joe = helloAfter('Joe', 3);
