If value is in multidimensional array

I'm having a problem with my $.getJSON function, first I store all my friends in a array like this:

var friends = [];
friends.push({
    user: {
        username: value.username,
        uuid: value.uuid,
        accepted: value.accepted,
        sent: value.sent
    }
});

This get's it's data from a $.getJSON function and works fine.

Then I have a search function, where I search for a username from my database like this:

$(document).on('keyup', '.search', function() {
        $.getJSON('url?username='+$(this).val(), function(data){
            $.each(data, function(index, value){
                friends.filter(function (friend) {
                    if(friend.user.username == value.username){
                       //Append custom
                    } else {
                        //append data from JSON
                    }
                });
            });
        });
    });

If friends array have a object, this works fine. But if it's empty, nothing happends, it does not append anything.

What's wrong here? Any help is appreciated

You should use filter to return the matching items in the array by evaluating whether your case is true.

var matches = friends.filter(function (friend) {
    return friend.user.username == value.username
});
if (matches.length > 0) {
    //you had a match in the friends array
    console.log(matches[0]);
} else {
    //you didn't have a match in the friends array
}

Here is a fiddle demonstrating the idea
