i have given exif of image split each key of json object , create sorted array it. output i'm expecting 

{   "app14":[     {"app14flags0": 16384},     {"app14flags1": 0},     {"colortransform": 1}   ],   "composite":[     {"aperture": 2.8}     {"circleofconfusion": 0.0309526315549036}     {"datetimecreated":  "2013:08:04 13:15:03+00:00"}     {"focallength35efl": 97.0717484087605}     {"..."}   ],   "sourcefile": "c.jpg",   "xmp":[     {"alreadyapplied": true},     {"approximatefocusdistance": 1.17},     {"autolateralca": 0},     {"blacks2012": 0}   ] }

my last console.log({key:values}); giving me same array. js fiddle

var the_keys =[]; _.foreach(data, function(n, key) {   //creating array of uniq keys   if(key.indexof(':')> -1) {     if (_.includes(the_keys, key.split(':')[0] ) == false) {       the_keys.push(key.split(':')[0]);      }   } else {     the_keys.push(key);   } });  console.log(the_keys);  _.foreach(the_keys, function(key) {   var values = []   _.foreach(data, function(k, n) {     if ((_.includes(the_keys, key.split(':')[0] ) ) || k == key) {       values.push(k);     }   });    console.log({key:values}); });

i'm splitting each keys cause create html table exif viewer site

give look. splitting key , building object piece piece. last token assigning value

_.foreach(data, function(v, k){     kparts = k.split(':');      var lastobj = returnobj;     for(var i=0; i<kparts.length - 1; i++){        var kpart = kparts[i]        if(!lastobj.hasownproperty(kpart)) lastobj[kpart] = {}        lastobj = lastobj[kpart];    }     lastobj[kparts[kparts.length - 1]] = v;  });
