How to combine values from different arrays of object into an array

Question

I want to capture the parameter Unassigned with value 64314 from the API output. My objective is to capture this information in an array such as ['Unassigned',64314]

I used this for-in loop to achieve the above.

var data = obj.rows;

for(var item in data){

 console.log(data[item].dimensionValues);
 console.log(data[item].metricValues);

}


//Output
[{
  value: "Direct"
}]
[{
  value: 1405211
}]....

But I am unable to map it to achieve this ['Unassigned',64314]. To me it seems I have to further loop the second level

//API Output

var obj = {
   "metricHeaders":[
      {
         "name":"sessions",
         "type":"TYPE_INTEGER"
      }

Answer 1

If dimentionaValues & metricValues going to have only one item, then you can specify 1st item and create array dynamically?

console.log([data[item].dimensionValues[0].value,data[item].metricValues[0].value]);

If they are of same length, you need another loop

for(var item in data){
  for(var i=0; i< data[item].dimensionValues.length;i++){
 console.log([data[item].dimensionValues[i].value,data[item].metricValues[i].value]);
  }
}

If they are of different length, you need to specify what logic in question.
