How to create a new array out of array of objects?

I have this JSON structure, I want to create 2 arrays out of this array of JSON. one array having all the values from key “employee only” to “”Annual OOP max / entire famliy” (from each object in JSON array) and 2nd array to have values from key “Primary care doctor visit” to end of the object”.

array 1 = [86.1, 291.3, 121.4 ………..6550,”$13,100 family”]

array 2 = [“75% covered after deductible”, “75% covered after deductible”,”$4 copay Doctor on Demand”,…………, “See HMO provider”] How can i achieve this in javascript?

Answer

You need something similar to this. Just add all the elements you want one by one as in the example below. Do the same for the other array (myArray is the json array)

var array1 = myArray.map(function(item) {
  return [item["employee Only"],
    item["employee + Spouse/Partner"],
    item["Annual OOP max / entire famliy"]
  ]
}).join(',').split(',');
