i have 2 objects this

var row = {     destination: {         id: 1,         name: 'test'     },     name: 'test2',     source: 'source2' }; var obj = [{'index': 'name'}, {'index': 'source'}, {'index': 'destination.name'}]; 

now looping on obj can values of row not destination.name

for(var i=0;i<obj.length;i++){     console.log(row[obj.index]); } 

output

test2 source2 undefined 

solution question

var row = {   destination: {     id: 1,     name: 'test'   },   name: 'test2',   source: 'source2' }; var obj = [  {'index': 'name'},   {'index': 'source'},   {'index': {'destination':'name'}} ];  for(var i=0;i<obj.length;i++){   if(typeof(obj[i].index) == 'object'){     var x = obj[i].index;     var key = object.keys(x)[0];     var innerkey = obj[i].index[key];     console.log(row[key][innerkey]);   } else {     console.log(row[obj[i].index]);   } }
