Converting a JSON array into an object representation

I have received some JSON data that has a specific structure:

[
{
    "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"
}
]

This JSON is stored in the variable 'newItem' and it is being processed in two different parts of the code I'm currently working on:

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

And later:

that.origCart.replaceWith(that.cart);

In the past, this process worked well when 'items' was flat. However, with our new JSON structure, I now need to handle 'items' within each category/name separately.

When iterating through a loop, I am able to access the individual items using:

newItem.items

But when trying to add these items to the cart, I encounter a Type Error. (I will eventually have multiple 'carts' once this issue is resolved.)

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

TypeError: newItem.items.toObject is not a function

Can anyone provide guidance on how to properly handle 'newItem.items' or suggest an alternative approach to setting them correctly? I have tried various solutions found online with no success, so I am reaching out to experts for assistance as this area is not my strong suit. Thank you.

Answer №1

It seems that you are attempting to access a function of an item from the newItems object, even though items is actually an Array. Please consider making the following modification:

that.shoppingCart.addItem(newItem.items);
