javascript compare two arrays of objects get same elements
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 compare arrays
Array.prototype.equals = function(arr2) {
return (
this.length === arr2.length &&
this.every((value, index) => value === arr2[index])
);
};
[1, 2, 3].equals([1, 2, 3]); // true
[1, 2, 3].equals([3, 6, 4, 2]); // falsecomparing 2 array
