What is better to use as iterable object in vue (generally in js)?

Question

JavaScript

Good afternoon.
Array vs Object? I understand that one can easily be converted to the other. But I would like to hear your opinion based on your experience. :)

// под Object-ом я понимаю следующее
mainNav = {
  create: {
    name: "create",
    title: "Создать",
    active: true
  },
  // ...
}

Answer 1

If order is important - Array
If you will access directly without loops - Object
Large lists - Map

Answer 2

An array is a special case of an object to which a number of methods have been added.
