DRY:

  let objArray = [
    {id: 0, name: 'Jonah',   otherProp:321},
    {id: 1, name: 'Andrew',  otherProp:648},
    {id: 2, name: 'Another', otherProp:850},
    {id: 3, name: 'Quite',   otherProp:146},
    {id: 4, name: 'Mary',    otherProp:984}
  ];

  let map = new Map(objArray.map((el) => [el.id, el]));
