index.js

const Indexer = require("basic-indexer").Indexer;

const index = new Indexer([
  {
    id: 1,
    name: "someName1",
  },
  {
    id: 3,

  },
  {
    id: 2,
    name: "someName2",
  },

Keeping the keys

const Indexer = require("basic-indexer").Indexer;

const index = new Indexer(
  [

    },
    {
      id: 3,

    },
    {
      id: 2,
      name: "someName",
    },
  ],
  "id",
  true
);

const values = index.get(1, 2, 3);
const array = index.getArray();
const allValues = index.getAll();

values contains:

[
  {
    id: 1,
    name: "someName",
  },
  {
    id: 2,
    name: "someName",
  },

  }
]

array contains:

[
  { id: 1, name: 'someName' },
  { id: 2, name: 'someName' },
  { id: 3, name: 'someName' }
]

allValues contains:

{
  '1': { id: 1, name: 'someName' },
  '2': { id: 2, name: 'someName' },
  '3': { id: 3, name: 'someName' }
}

value contains:

{ id:1, name: 'someName' }
