Hello I receive the JSON as follows:

[
  {
    "degreesC": 18.39599609375,
    "device_id": "test-dev1",
    "humidity": 40.6005859375,
    "raw": "421/dg==",
    "time": "2019-11-11T21:16:31.633569185Z"
  },
  {
    "degreesC": 19.6044921875,
    "device_id": "test-dev1",
    "humidity": 37.98828125,
    "raw": "Rm4Udg==",
    "time": "2019-11-11T21:40:20.87571354Z"
  }
]

How can I parse it I have problems to access because of [ ].
I use var obj = JSON.parse(testi); testi is the JSON above.
But this don’t work when obj.time
Could somebody help me?
