“JavaScript vergleichen zwei Arrays von Objekten” Code-Antworten

JavaScript vergleicht zwei Arrays von Objekten, die die gleichen Elemente erhalten

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

JavaScript vergleichen zwei Arrays von Objekten

//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);
