How to append to json object in JavaScript

Question

How can I append to a json object.

I define the JSON as follows:

$scope.usergroupJson = {'groupId':1,'name':'CEO'}

I would like to append {'groupId':2,'name':'Director'} to the usergroup. I have tried:

$scope.usergroupJson.push({'groupId':2,'name':'Director'});

But I get an undefined error. I know this is trivial but any help would be appreciated. Thanks in advance

We can use like this var json = {}; json["employees"] = [];

var usergroupJson = json["employees"];
usergroupJson.push({
    'groupId': 1,
    'name': 'President'
});
usergroupJson.push({
    'groupId': 2,
    'name': 'Vice-President'
});
usergroupJson.push({
    'groupId': 3,
    'name': 'Product Manager'
});

$scope.usergroupJson = [{'groupId':1,'name':'CEO'}]

Thanks tried that but it is not what I am after. I would like maintain the JSON format. If I do this I end up getting something in the form of: [0], [1] I would like to get in the form: w3schools.com/json
