Dynamically calculate the average for a nested collection using lodash

Question

I have a JSON array of objects (a collection) like:

[{
  \"x\": {
        \"x1\": 1
  },
  \"y\": {
    \"yt\": 0,
    \"zt\": 4,
    \"qa\": 3,
    \"ft\": 0,
          


        

Answer 1

var array = [{
  "x": {
        "x1": 1
  },
  "y": {
    "yt": 0,
    "zt": 4,
    "qa": 3,
    "ft": 0
  }
},
{
  "x": {
        "x1": 5
  },
  "y": {
    "yt": 10,
    "zt": 2,
    "qa": 0,
    "ft": 0
  }
}];
function aintob(){
  var o = {};
  var first = array[0],
      second = array[1];
  var result = {x:{},y:{}};
  var each = function(letter, oa, ob){
    var i,
    letter = {};
    for(i in oa){
      letter[i] = (oa[i]+ob[i])/2;
    }
    return letter;
  }
  o.x = each("x", first.x, second.x);
  o.y = each("y", first.y, second.y);
  return o;
}
console.log(aintob());
