Javascript object notation -

-

i did manipulations , stored values in arrays say, miles , type. need display object own specific properties. have 

obj ={      "miles" : [500,200],      "type": ["fer","bug"]  };

i need return object in format 

obj = {      "fer" : 500 ,      "bug" : 200  };

thanks. idea appreciated!

iterate , create new object

var obj = { "miles" : [500,200], "type": ["fer","bug"] };        var obj2 = {};        (var i=0; i<obj.type.length; i++) {      obj2[obj.type[i]] = obj.miles[i];  }    // snippet output  document.body.innerhtml = '<pre>' + json.stringify(obj2, null, 4) + '</pre>';
