I have an array of objects and want to combine them into one object IF the one of the keys match(in this case the "date" key)

```
    Array [
  Object {
    "date": "2020-07-14",
    "finishTime": "22:00",
    "startTime": "13:30",
  },
  Object {
    "date": "2020-07-14",
    "finishTime": "12:00",
    "startTime": "08:00",
  },
]

```

Expected output should be

```
 Array [
  Object {
    "date": "2020-07-14",
    "finishTime": ["22:00", "12:00"]
    "startTime": ["13:30", "08:00"]
  },

```
