i have these 3 array

[
  { animals: 'dog', user_id: 12, y: 1 },
  { animals: 'cat', user_id: 1, y: 3 }
]

[
  { Habitation: 'Appartement',  user_id: 1, y: 1 },
  { Habitation: 'Mansion', user_id: 12, y: 1 },
  { xHabitation: 'House', user_id: 1, y: 2 }
]

[
  { device : 'computer', user_id: 1, y: 1 },
  { device : 'laptop', user_id: 1, y: 2 },
  { device : 'tablet', user_id: 12, y: 1 }
]

So these 3 array have something in common : user_id

And i want to create something like this

[
  1 = {
      pets : [{ x: 'cat', y: 3 }],
      house: [{ x: 'Appartement', y: 1 },  { x: 'House', y: 2 }],
      device: [{ x: 'computer', y: 1 },   { x: 'laptop', y: 2 }]
    },
  12 = {
     pets : [{ x: 'dog', y: 1 }],
     house: [{ x: 'Mansion', y: 1 }],
     device: [{ x: 'tablet', y: 1 }]
   }
]

As you can see object are created based on user_id, i dont see/know how to perform a clean code for that in native javascript

Thanks
