Below is my object:
var obj = {
    'test': {
        'id1': 1,
        'id2': 2,
        'id3': 3
    }, 'test2': {
        'id4': 4,
        'id5': {
            'id123': 3,
            'id456': 6
        }
    },
    'test3': 45,
    'test4': 55
}
I am trying to write a recursive function for getting nested properties in the format like.
test.id1, test2.id5.id123 etc...
But I am not getting properties which are nested as shown above.
Below is my function
function getKey(obj, key) {
    var keyArr = [];
    var newKey = key;
    var data=newKey;
    if (_.isObject(obj[key])) {
      _.each(_.keys(obj[key]), function(singleKey) {
        newKey =  data + '.'+ getKey(obj[key], singleKey);
        return newKey
      });
    }
    return keyArr.length ? keyArr : newKey;   
  }
I am calling this function like var keys = _.keys(obj); _.each(keys, function(key) { getKey(obj, key); }
Can anyone help with this issue? Thanks
