var originalArray = [
{
name: 'Shop1',
stock: [
{ name: 'Apples', quantity: [{ id: "something", time: 11 }, { id: "something", time: 44 }, { id: "something", time: 53 }] },
{ name: 'Bananas', quantity: [{ id: "something", time: 3 }, { id: "something", time: 91 }, { id: "something", time: 3 }] },
{ name: 'Grapes', quantity: [{ id: "something", time: 2 }, { id: "something", time: 91 }, { id: "something", time: 3 }] },
{ name: 'Pineapple', quantity: [{ id: "something", time: 8 }, { id: "something", time: 91 }, { id: "something", time: 3 }] }
]
},
{
name: 'Shop2',
stock: [
{ name: 'Laptop', quantity: [{ id: "something", time: 31 }, { id: "something", time: 11 }, { id: "something", time: 23 }] },
{ name: 'Phone', quantity: [{ id: "something", time: 1 }, { id: "something", time: 11 }, { id: "something", time: 23 }] },
{ name: 'Tablet', quantity: [{ id: "something", time: 111 }, { id: "something", time: 11 }, { id: "something", time: 323 }] }
]
}
];
For instance, in the provided array, stock and quantity are nested keys with an array of objects as their value.
Shop2 has
{ id: "something", time: 323 }Shop1After sorting,
Shop2 will be first in the list and Shop1 will be in second position, and so on, time descending
My code is not correctly sorting the shops.
It should not sort the nested array in stock & quantity, just sort the Shop order by time descending
const sorted = originalArray
.map(shop => shop.stock
.map(stk => stk.quantity
.map(item => Object.entries(item)[1])))
.sort((a, b) => b[1].time - a[1].time)
.map(item => item[1])
console.log(JSON.stringify(sorted));
EXPECTED OUTPUT
// sorted array

name: 'Shop2',

{ name: 'Laptop', quantity: [{ id: "something", time: 31 }, { id: "something", time: 11 }, { id: "something", time: 23 }] },
