If you don't want to use any framework, thats the code:

function mix(first_arr, second_arr) {
    for(i = 0; i < second_arr.length; i++) {
        if(first_arr.indexOf(second_arr[i]) == -1) {
            first_arr.push(second_arr[i]);
        }
    }
    return first_arr;
}

PD: Use arrays [] instead of objects {}
