How to transform an array into an object in javascript

Question

I have an array like this:

[
{ id: "Идент", name: "Назв", price: "Сто", quantity: "Коло" },
[ 1, "продукт 1", "400", 5 ],
[ 2, "продукт 2", "300", 7 ],
[ 2, "продукт 2", "300", 7 ]]

How can I transform it into something like this:

{
 items: [
 { name: "Хлеб", id: 1, price: 15.9, quantity: 3 },
 { name: "Масло", id: 2, price: 60, quantity: 1 },
 { name: "Картофель", id: 3, price: 22.6, quantity: 6 },
 { name: "Сыр", id: 4, price:310, quantity: 9 }
 ]
};

• Nina Scholz: how do you match produkt with kartofel?
• Hackerman: Your array has different data, compared with your expected output...apart from that, this is an easy task....

Answer 1

I assume that index 0:id,1:name,2:price,3:quantity. here you go,

var array = [
 [12,"abc",232,2],
 [12,"abc",232,2],
 [12,"abc",232,2],
 [12,"abc",232,2]
 ];
 var obj = {};
 obj.options = (function(array){
 var e = [];
 for(i in array){
 t = {};
 t.id = array[i][0];
 t.name = array[i][1];
 t.price = array[i][2];
 t.quantity = array[i][3];
 e.push(t);
 }
 return e;
 })(array);
 console.log(obj)

To convert an array with data to an array with objects, you could use another array with keys and iterate it for the assignment of the properties for the new objects.

var data = [{ id: 'id', name: 'name', price: 'price', quantity: 'quantity' }, [0, 'foo', 1.99, 201], [1, 'abc', 2.5, 42], [2, 'baz', 10, 99], [6, 'bar', 21.99, 1]],
 keys = Object.keys(data[0]), 
 result = {
 items: data.slice(1).map(function (a) {
 var temp = {};
 keys.forEach(function (k, i) {
 temp[k] = a[i];
 });
 return temp;
 })
 };
 
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
