I've got this set of data :

  { CIRPIC: 'AUA', ALLPIC: 2 },
  { CIRPIC: 'AUA', ALLPIC: 3 },
  { CIRPIC: 'AUA', ALLPIC: 1 },
  { CIRPIC: 'AUA', ALLPIC: 4 },
  { CIRPIC: 'AUF', ALLPIC: 12 },
  { CIRPIC: 'AU3', ALLPIC: 2 },
  { CIRPIC: 'AU3', ALLPIC: 7 },

And I would like it to be like this :

{CIRPIC: 'AUA', ALLPIC: [2,3,1,4]},
{CIRPIC: 'AUF', ALLPIC: [12]},
{CIRPIC: 'AU3', ALLPIC: [2,7]},

Thanks for your help

Please show us what you tried to solve this problem. – Ghassen Louhaichi May 05 '22 at 17:18
I don't understand how to implement it with my code, Ghassen – stackmotherfcker May 05 '22 at 17:21
I think what you are looking for is reduce method. https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce – Jimmy Gonçalves May 05 '22 at 17:23
[This answer](https://stackoverflow.com/a/33850667/479156) does what you want. Just change `name` to `CIRPIC`, `value` to `ALLPIC` and `'string'` to `'number'`. – Ivar May 05 '22 at 17:28
