Answer 1

Using ES6 solution

For those still reading this answer, if you are using ES6 the find method was added in arrays. So assuming the same collection, the solution'd be:

const foo = { "results": [
    {
        "id": 12,
        "name": "Test"
    },
    {
        "id": 2,
        "name": "Beispiel"
    },
    {
        "id": 3,
        "name": "Sample"
    }
] };
foo.results.find(item => item.id === 2)

I'd totally go for this solution now, as is less tied to angular or any other framework. Pure Javascript.

Angular solution (old solution)

I aimed to solve this problem by doing the following:

$filter('filter')(foo.results, {id: 1})[0];

A use case example:

app.controller('FooCtrl', ['$filter', function($filter) {
    var foo = { "results": [
        {
            "id": 12,
            "name": "Test"
        },
        {
            "id": 2,
            "name": "Beispiel"
        },
        {
            "id": 3,
            "name": "Sample"
        }
    ] };

    // We filter the array by id, the result is an array
    // so we select the element 0

    single_object = $filter('filter')(foo.results, function (d) {return d.id === 2;})[0];

    // If you want to see the result, just check the log
    console.log(single_object);
}]);
