function placeGuests (arr) {
 let result = [arr[0]];
 let currentUser = arr[0];
  
while(arr.length!==result.length){
  arr.forEach(el => el.close.sort((a,b) => 
     a > b ? 1 : -1
  ))
  let closeFilter = currentUser.close.filter(closeName => 
         !result.find(friend => 
         closeName === friend.name))

 let user = arr.find(el => el.name === closeFilter[0])
 currentUser = user
      result.push(user)
}     
  return result;
}

Я такой код написал) Всех с Новым годом!
