I'm trying to get single object with different item based by the id from compared result of two array of objects.

Here's the case:

First Array

[
    {
        "id": "792657571767910421",
        "type": 0,
        "allow": "0",
        "deny": "0"
    },
    {
      "id": "1020443938668171294",
      "type": 0,
      "allow": "0",
      "deny": "377959221312"
    },
    {
      "id": "791708642813411358",
      "type": 0,
      "allow": "0",
      "deny": "0"
    }
]

Second Array

[
    {
      "id": "792657571767910421",
      "type": 0,
      "allow": "1024",
      "deny": "0"
    },
    {
      "id": "1020443938668171294",
      "type": 0,
      "allow": "0",
      "deny": "377959221312"
    },
    {
      "id": "791708642813411358",
      "type": 0,
      "allow": "0",
      "deny": "0"
    },
]

Expected Output

[
    {
      "id": "792657571767910421",
      "type": 0,
      "allow": "1024",
      "deny": "0"
    },
]

Different value

// First array
{
    "allow": "0"
}

// Second array
{
    "allow": "1024"
}

Can anyone help me? Thank you.

You will have to use custom filter logic:

Logic:

• Loop over arr2 or the array you need output from.
• Test items with param2. On match:
  • Loop over arr1 or the other array.
  • Find the object with same ID.
  • On finding,
    • Test item with param1. Return test value.
  • Else return false

function filter(arr1, arr2, param1, param2) {
  const test = (param, item) =>
    Object
      .entries(param)
      .every(([k, v]) => item[k] === v)

  return arr2.filter((itemB) => {
    if (test(param2, itemB)) {
      const itemA = arr1.find(({id}) => id === itemB.id)
      return !!itemA ? test(param1, itemA) : false
    }
    return false
  })
}

const arr1 = [{"id": "792657571767910421","type": 0,"allow": "0","deny": "0"},{"id": "1020443938668171294","type": 0,"allow": "0","deny": "377959221312"},{"id": "791708642813411358","type": 0,"allow": "0","deny": "0"}]
const arr2 = [{"id": "792657571767910421","type": 0,"allow": "1024","deny": "0"},{"id": "1020443938668171294","type": 0,"allow": "0","deny": "377959221312"},{"id": "791708642813411358","type": 0,"allow": "0","deny": "0"},]

const param1 = {"allow": "0"}
const param2 = {"allow": "1024"}

console.log(filter(arr1, arr2, param1, param2))
