Writing JSON array to object

I have some JSON which looks like this.

[
{
    "items": [
        {
            "id": "xxxx",
            "description": {
                "style": "",
                "specs": ""
            }
        },
        {
            "id": "xxxx",
            "description": {
                "style": "",
                "specs": ""
            }
        }
    ],
    "category": "xxxxxx",
    "name": "xxxxxx"
},
{
    "items": [
        {
            "id": "xxxx",
            "description": {
                "style": "",
                "specs": ""
            }
        },
        {
            "id": "xxxx",
            "description": {
                "style": "",
                "specs": ""
            }
        }
    ],
    "category": "xxxxxx",
    "name": "xxxxxx"
}
]

It's being passed to me as 'newItem'. And is being set twice in the existing code I'm working on:

that.cart.addItem(newItem.toObject());

And later:

that.origCart.replaceWith(that.cart);

This traditionally has worked fine when 'items' was a flat list. However, the JSON above is the new JSON format and therefor I need to pass 'items' for each category/name.

Inside the 'for' loop I have this outputting what I need for each.(I need to keep them separated.)

newItem.items

However, when I attempt to perform the following I get a Type Error. (Yes, I'm going to have multiple 'carts' once I get this working.)

that.cart.addItem(newItem.items.toObject());

TypeError: newItem.items.toObject is not a function

What can I do to get 'newItem.items' to the proper type, or what operation can I substitute for to get these set properly? I tried a bunch of things I found online without success and now I'm turning to the experts. Just not my forte (yet).

It looks like you're trying to call an items function from the newItems object even though items is an Array. Try the following:

that.cart.addItem(newItem.items);
