This is the array

[  
   {  
      "contest_id":1,
      "points":10
   },
   {  
      "contest_id":2,
      "points":10
   },
   {  
      "contest_id":1,
      "points":11
   },
   {  
      "contest_id":2,
      "points":9
   },
   {  
      "contest_id":1,
      "points":12
   }
]

In the above array contains list of objects, sort the array of objects based property values like contest_id with ascending order , points are descending order . Output :-

Contest_id    points

1             12
1             11
1             10
2             10
2             9

`list.sort((a,b) => a.contest_id< b.contest_id? 1 : a.contest_id> b.contest_id?-1:a.points>b.points?1:a.points – Eliseo Jun 14 '19 at 08:31
