Extract specific data from JSON string

Question

JSON:

{
  "trackResponse": {
    "shipment": [{
      "warnings": [{
        "code": "TW",
        "message": "Tracking Information Not Found"
      }]
    }]
  }
}

In that string I want to retrieve "message" information. Please let know

use flatMap and Map

var data = {
  "trackResponse": {
    "shipment": [{
      "warnings": [{
        "code": "TW",
        "message": "Tracking Information Not Found"
      }]
    }]
  }
};
console.log(data.trackResponse.shipment.flatMap(i=>i.warnings.map(m=>m.message)))

FYI, You are extracting it from an object, the question was about JSON...so You are missing a line ;) – vanowm Apr 15 '21 at 21:31
Can we do this without flatmap and map – Deepu Apr 16 '21 at 06:11
