Challenge: Manage Element Properties and Attributes

Task

You're working on a product page where you'll display product information and allow users to toggle the availability status.

  1. Set product name to "Smartphone";
  2. Set the initial price to "499.99";
  3. Toggle Availability Status Using Attributes: When the button is clicked:
    • Check if the <button> has the attribute data-available;
    • If data-available is present, remove it and update the text content to "Unavailable".
    • If data-available is absent, add it with a value of "true" and update the text content to "Available".
  4. Display the Availability Status:
    • Check if the data-available attribute is present on the button;
    • Display "In Stock" in availability-status if data-available is present, or "Out of Stock" if it's absent.
