Object from array

There is an array of users:

users = [
  {
    id: 'as23'
    nick: 'Octopus',
    firstName: 'John',
    LastName: 'Dou'
  }, {
    id: 'as25'
    nick: 'Star',
    firstName: 'Andy',
    LastName: 'Lee'
  }, {
    id: 'as77'
    nick: 'Wally',
    firstName: 'Liza',
    LastName: 'Corty'
  }
]

Property 'id' of all array elements is always unique (id: 'as23'). Transform this array into an object where object's property key is this id, and value is the array item itself. { 'as23' : {} }
