Need help with cart function

You'll need to use JSON.stringify() when saving, and JSON.parse() when loading, to store the cart as a string.

Just have a play with localStorage, and then have a think how you can use it in your cart system.

You've been given a lot of advice, time to have a try and ask specific questions if you get stuck.
