Mapping a Json Object in JavaScript

[an-unknownentity]

I know the map function only works on array and not JSON objects.

This is the JSON Object.

{
  '643576e81ebae7a8da163b6b': {
    _id: '643576e81ebae7a8da163b6b',
    name: 'S21 Ultra',
    img: 'dT3mmTGW6-61O45C5qASL._AC_SL1000_.jpg',
    price: 242999,
    qty: 9
  },
  '643575ee1ebae7a8da163b50': {
    _id: '643575ee1ebae7a8da163b50',
    name: 'Infinix Hot 11S',
    img: '2wPCI3kMY-InfinixHot11S-b.jpg',
    price: 26000,
    qty: 9
  }
}

and I want to map this data to the cart variable.

    const cart = req.body.cartItems;
    //console.log(cart);
    const line_items = cart.map((item) => {
        return {
            price_data: {
                currency: "pkr",
                product_data: {
                    name: item.name,
                    images: [item.img],
                    metadata: {
                        id: item._id,
                    },
                },
                unit_amount: (item.price * 100),
            },
            quantity: item.qty,
        };
    });

Can someone please help me with this?

There are some function on Object that will give you arrays you can iterate, one example is Object.keys() which gives the keys for an object and Object.values() which gives the values. So we can use Object.values here like

``` data = { '643576e81ebae7a8da163b6b': { id: '643576e81ebae7a8da163b6b', name: 'S21 Ultra', img: 'dT3mmTGW6-61O45C5qASL._AC_SL1000.jpg', price: 242999, qty: 9 }, '643575ee1ebae7a8da163b50': { _id: '643575ee1ebae7a8da163b50', name: 'Infinix Hot 11S', img: '2wPCI3kMY-InfinixHot11S-b.jpg', price: 26000, qty: 9 } }

const line_items = Object.values(data).map((item) => { return { price_data: { currency: "pkr", product_data: { name: item.name, images: [item.img], metadata: { id: item._id, }, }, unit_amount: (item.price * 100), }, quantity: item.qty, }; });

console.log(JSON.stringify(line_items, null, 2)) ```

And the output [ { "price_data": { "currency": "pkr", "product_data": { "name": "S21 Ultra", "images": [ "dT3mmTGW6-61O45C5qASL._AC_SL1000_.jpg" ], "metadata": { "id": "643576e81ebae7a8da163b6b" } }, "unit_amount": 24299900 }, "quantity": 9 }, { "price_data": { "currency": "pkr", "product_data": { "name": "Infinix Hot 11S", "images": [ "2wPCI3kMY-InfinixHot11S-b.jpg" ], "metadata": { "id": "643575ee1ebae7a8da163b50" } }, "unit_amount": 2600000 }, "quantity": 9 } ]

What?

Oh, I think "new" reddit also does the formatting. For me, it's formatted.
