There is no JSON in this question. That's a JavaScript object. JSON is a format, and is always a string. — Cerbrus, Aug 01 '18 at 12:10
JSON != JavaScript. What you have is a JavaScript object not a string of JSON formatted data. — phuzi, Aug 01 '18 at 12:11

Is this what you are looking for?

let data = [{
  "king": [{
      "id": 1,
      "room_no": 101,
      "price": 2000
    },
    {
      "id": 2,
      "room_no": 102,
      "price": 3000
    },
  ]
}]

data[0].king.forEach(item => console.log(item.room_no));

It does the job (well, not quite. It doesn't output the room number), but don't use `.map`. That's not its purpose. Use `.forEach`. – Jeremy Thille Aug 01 '18 at 12:13
Here, I updated it. – Shaurya Dhadwal Aug 01 '18 at 12:15
Still using `.map` for no reason, though – Jeremy Thille Aug 01 '18 at 12:16

Hey @JeremyThille. Thanks for the upvote. I would have never gone and looked for the scenarios of foreach and map if you wouldn't have pointed out. So I just read a few posts on it. I guess one is always learning, thanks. – Shaurya Dhadwal Aug 01 '18 at 12:21
