How to change Key of an object dynamically

I have an object like this:

var obj{};

I want to set object values dynamically like so:

for(i=0;i<10;i++)
{
quest='quest'+i;
header='header'+i;
$(obj).data(quest,{header:i});
quest,header=0;
}

I'm expecting object to be saved like: 

obj{quest1:{header1:1},
quest2:{header2:2}
quest3:{header3:3}

But they are saved like:

obj{quest1:{header:1},
quest2:{header:2},
quest3:{header:3},

The header-key in my object is not getting the actual value. but simply save as "header"..

Could you please guide me here?

You can write:

var obj = {};

for(i=1; i<11; i++) {
   quest='quest'+i;
   header='header'+i;
   obj[quest] = {};
   obj[quest][header] = i;
}

In your code your loop starts with i = 0 but the properties start by 1.

var quest, header, obj = {};

for (i = 0; i < 10; i += 1) {
  quest = 'quest' + (i + 1);
  header = 'header' + (i + 1);
  obj[quest] = {};
  obj[quest][header] = (i + 1);
}

You cannot have a variable key in an object literal.
