//Find values that are in result1 but not in result2
var uniqueResultOne = result1.filter(function(obj) {
    return !result2.some(function(obj2) {
        return obj.value == obj2.value;
    });
});

//Find values that are in result2 but not in result1
var uniqueResultTwo = result2.filter(function(obj) {
    return !result1.some(function(obj2) {
        return obj.value == obj2.value;
    });
});

//Combine the two arrays of unique entries
var result = uniqueResultOne.concat(uniqueResultTwo);
