How to add object into object in javascript

Question

I am aware there is push() to add oject into array. But how to add object into object.

var osubcategories = {};

for (var i=0; i<data.length; ++i){
      var tempkey = data[i].scid;   // here tempkey will be any number sat 15 20 30 etc

      // how to add this tempkey along with true in osubcategories
 }

I want output like this for each tempkey in loop:

osubcategories = {"15" : true, "23": true, "55" : true}

EDIT: forgot tempkey

I am not sure I get your comment. – Pep. Aug 15 '16 at 08:17
The tempkey should be a temporary key. In cases, you want to keep the keys unique when used in functions/code. Decent answer though. :) – Adam Azad Aug 15 '16 at 08:18

var osubcategories = {};
for (var i=0; i<data.length; ++i){
  var tempkey = data[i].scid;   // here tempkey will be any number sat 15 20    30 etc
  // the following line will add the properties to the "osubcategories" object
  osubcategories[tempKey] = true;
}
