Add information to an array with no specific index

Can anyone help me figure out how to insert the following object into an array called "posts"?

{ post_id: 1, text: "text", creation: "date" }

I have a complex array structure like this:

 var posts = [

    {
        post_id: 5, 
        text: "text", 
        creation: "date"
    },
    {
        group: "favPosts",
        posts: [
                    { post_id: 2, text: "text", creation: "date" }, 
                    { post_id: 7, text: "text", creation: "date" }
               ]
    },
    {
        post_id: 8, 
        text: "text", 
        creation: "date"
    }
]

I've tried various methods like slice and push but couldn't quite get it working. I'm still learning JavaScript and struggling with this task.

While I did come up with a solution using a function called addToGroup, I believe it's not very efficient:

addToGroup("favPosts");

function addToGroup(group) {

    for(id in posts) {

        if(posts[id].group == group){

            posts[id].posts.push({ post_id: 10, text: "did it", creation: "date" });

            console.log(posts[id]);
        }
    }
}

Utilizing a push method should do the trick, there doesn't seem to be any reason why it wouldn't work. For instance, you can see an example below where Angular is used for easy HTML display, although it may not be necessary for your specific task:http://plnkr.co/edit/PBCYxfjMqV3jzggMHJZ7?p=preview

var people = [
    {
        name: "Joe",
        surname: "surname"
    },
    { 
        group: "name",
        people: [{ name: "name", surname: "surname" }, { name: "name", surname: "surname"     }]
    },
    {
        name: "James",
        surname: "surname"
    }
];

var person = { name: "Jennifer", surname: "surname" };

people.push(person);
