Answer 1

Something like this:

let array = [
    {"City": "Hamburg"},
    {"City": "Berlin"},
    {"City": "Berlin"},
    {"City": "Stuttgart"},
    {"City": "Augsburg"}
];
array.sort(function (a, b) {
    if (a.City === "Berlin")
        return -1;
    if (b.City === "Berlin")
        return 1;
    if (a.City < b.City) {
        return -1;
    }
    if (a.City > b.City) {
        return 1;
    }
    return 0;
});
console.log(array);
