Problem 1

All code will be written in index.js. Be sure to run npm install before getting started. Open index.html to view your output.

Do not assume the data will always be in the exact format provided. Commit your code between each step.

1. Update the mutateArray function to return a as a flattened array, so that each item is changed to

{
  'guest_type': 'crew',
  'first_name': 'Marco',
  'last_name': 'Burns',
  'room_no': 'A0073',
  'some_array': [
    7,
    2,
    4
  ]
},

2. Now update the mutateArray function so that the 'some_array' attribute in each item of the mutated array is changed to the sum of the array called 'some_total'

{
  'guest_type': 'crew',
  'first_name': 'Marco',
  'last_name': 'Burns',
  'room_no': 'A0073',
  'some_total': 13
},

3. Now update the mutateArray function so that the resulting array only includes objects with a guest_type of 'guest'.

4. Finally, update the mutateArray function so the resulting array is ordered alphabetically by last and first name.

The final result should look like this:

[
  {
    "guest_type": "guest",
    "first_name": "Jane",
    "last_name": "Doe",
    "room_no": "C73",
    "some_total": 18
  },
  {
    "guest_type": "guest",
    "first_name": "John",
    "last_name": "Doe",
    "room_no": "C73",
    "some_total": 18
  },
  {
    "guest_type": "guest",
    "first_name": "Albert",
    "last_name": "Einstein",
    "room_no": "B15",
    "some_total": 16
  },
  {
    "guest_type": "guest",
    "first_name": "Alan",
    "last_name": "Turing",
    "room_no": "B15",
    "some_total": 16
  }
]
