How to merge two objects with different structure in javascript

Question

I Have two objects with different structure, trying to merge this two objects with matched data based on a key value, and make a new object with complete data from object1 and object2.

my Object1

{  
   "schedule":{  
      "onward":{  
         "journey":[  
            {  
               "trips":[  
                  {  
                     "origin":{  
                        "airportCode":"AMS"
                     },
                     "destination":{  
                        "airportCode":"BCN"
                     },
                     "FlightNumber":"KL1665"
                  }
               ]
            },
            {  
               "trips":[  
                  {  
                     "origin":{  
                        "airportCode":"AMS"
                     },
                     "destination":{  
                        "airportCode":"BCN"
                     },
                     "FlightNumber":"MF9343"
                  }
               ]
            }
         ]
      }
   }
}

object 2

{  
   "flights":[  
      {  
         "flightNumber":"KL1665",
         "price":223,
         "available":10
      },
      {  
         "flightNumber":"KL112",
         "price":223,
         "available":10
      },
      {  
         "flightNumber":" KL112",
         "price":223,
         "available":10
      }
   ]
}

i Would like to merge "price" and "available" to object which matches with "flightNumber" and create a new object with all data.

I have tried to use loadash and underscore but couldnt figure it. Help would be great, Thank in Advance.

Answer 1

2 simple forEach will do it:-

flights.flights.forEach(function(e, i) {
  schedule.schedule.onward.journey.forEach(function(e2, i2) {
    if (e.flightNumber == e2.trips[0].FlightNumber) {
      e2.trips[0] = $.extend(e, e2.trips[0]);
    }
  });
});

Working example:

 var schedule = { "schedule": { "onward": { "journey": [{ "trips": [{ "origin": { "airportCode": "AMS" }, "destination": { "airportCode": "BCN" }, "FlightNumber": "KL1665" }] }, { "trips": [{ "origin": { "airportCode": "AMS" }, "destination": { "airportCode": "BCN" }, "FlightNumber": "MF9343" }] }] } } }; var flights = { "flights": [{ "flightNumber": "KL1665", "price": 223, "available": 10 }, { "flightNumber": "KL112", "price": 223, "available": 10 }, { "flightNumber": " KL112", "price": 223, "available": 10 } ] }; flights.flights.forEach(function(e, i) { schedule.schedule.onward.journey.forEach(function(e2, i2) { if (e.flightNumber == e2.trips[0].FlightNumber) { e2.trips[0] = $.extend(e, e2.trips[0]); } }); }); console.log(schedule);
