I have an object array like this:

```
var input = [{ time: '11:01:00', data: 'a,b,c' }, { time: '11:01:11', data: 'a,b,c' }]

```

After I call:

```
var output1 = input.map(a => a.data);
console.log(output1);

```

The result would be:

```
[
  "a,b,c",
  "a,b,c"
]

```

Now I want the final output will be:

```
[
  {data: ["a","a"]},
  {data: ["b","b"]},
  {data: ["c","c"]},
]

```

I have tried many way but no hope to do this.
