How can I compare multiple arrays of objects and add new properties with the number of occurrences an object was found and the array indexes where the object was found?
The object comparison must be made by the `name` property.

Example:

```
var arrays = [
  [
    {
      name: 'aa',
      value: 1
    },
    {
      name: 'ab',
      value: 2
    },
    {
      name: 'ac',
      value: 3
    },
    {
      name: 'aa',
      value: 1
    }
  ],
  [
    {
      name: 'aa',
      value: 1
    },
    {
      name: 'ab',
      value: 2
    },
  ],
  [
    {
      name: 'ac',
      value: 3
    },
    {
      name: 'aa',
      value: 1
    }
  ]
]

```

After execution the object from the above array should have these properties:

```
[
  [
    {
      name: 'aa',
      value: 1,
      occurrences: 3,
      where: [0, 1, 2]
    },
    {
      name: 'ab',
      value: 2,
      occurrences: 2,
      where: [0, 1]
    },
    {
      name: 'ac',
      value: 3,
      occurrences: 2,
      where: [0, 2]
    },
    {
      name: 'aa',
      value: 1,
      occurrences: 3,
      where: [0, 1, 2]
    }
  ],
  [
    {
      name: 'aa',
      value: 1,
      occurrences: 3,
      where: [0, 1, 2]
    },
    {
      name: 'ab',
      value: 2,
      occurrences: 2,
      where: [0, 1]
    }
  ],
  [
    {
      name: 'ac',
      value: 3,
      occurrences: 2,
      where: [0, 2]
    },
    {
      name: 'aa',
      value: 1,
      occurrences: 3,
      where: [0, 1, 2]
    }
  ]
]

```

Basically I want to check if the object with a specific `name` property exists in the other arrays.

This is the solution that comes in my mind:
 1. Loop through the array that has the most objects  

 2. Loop through each object  

 3. Loop through the other arrays and apply `Array.prototype.find()`  

But this will take a lot of time since each of my array will have at least 500 objects...
