Access Cart attributes / Order Notes on Order Status Page (javascript object, not liquid)

How can I access cart attributes or order notes on order status page with javascript (not liquid vars)?

I understand the checkout object is accessible on order status page, and it has lots of information about the order. However, cart attributes / order notes are not included in the checkout object. I understand it’s available to liquid but I’m trying to access the order attribute from a scriptTag, so I can’t use liquid vars because scriptTag doesn’t have access to liquid vars

Ok wow. Cart.js to the rescue yet again! I have already implemented Cart.js in my app to make it easy to add the cart attribute. I forgot the CartJS.cart object would be available on the order status page, and it contains the attribute I need access to!
