如何将map对象列表转化为arrays数组

Question

I have an array of objects that I need to reformat into a list of arrays in a specific format.

I need my list to be formatted like this

list: [
        [ "B", "A" ],
        [ "F", "E" ],
    ]

But the closest I have come is this

list: ["B A", "F E"]

using this code

const itemList = [
    {"ProductName":"A",
        "Sku":"B",},
    {"ProductName":"E",
        "Sku":"F",}
];

const newList = itemList.map(item => `${item.Sku} ${item.ProductName}`);

console.log(newList);

How would I map this correctly?

Answer 1

You can create array with the values inside map:

 const itemList = [ {"ProductName":"A", "Sku":"B",}, {"ProductName":"E", "Sku":"F",} ]; const newList = itemList.map(item => [item.Sku, item.ProductName]); console.log(newList);

Answer 2

You can also use destucure for each item and map it to array of these values:

 const itemList = [ { ProductName: 'A', Sku: 'B' }, { ProductName: 'E', Sku: 'F' } ]; const newList = itemList.map(({ProductName, Sku}) => [ Sku, ProductName ]); console.log(newList);

Answer 3

To keep things simple, I would use Object.values as such:

const newList = [];
itemList.map(item => newList.push(Object.values(item)));
