How does lodash.xorWith work?

lodash.xorWith is a function in the Lodash library that takes in two arrays and a comparator function, and returns an array of unique values that are present in only one of the input arrays, as determined by the comparator function.

//_.xorWith(array,[comparator])
let xorWith1 = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }];
let xorWith2 = [{ 'x': 1, 'y': 1 }, { 'x': 1, 'y': 2 }];
let xorWith3 = _.xorWith(xorWith1, xorWith2, _.isEqual);
console.log('xorWith3--->', xorWith3);
//xorWith3---> [ { x: 2, y: 1 }, { x: 1, y: 1 } ]

const _ = require("lodash");

const array1 = [
  { x: 1, y: 2 },
  { x: 2, y: 1 },
];
const array2 = [
  { x: 1, y: 2 },
  { x: 2, y: 1 },
  { x: 3, y: 3 },
];

const result = _.xorWith(array1, array2, _.isEqual);
console.log(result); // [{ x: 3, y: 3 }]

In this example, lodash.xorWith is used to find the symmetric difference between two arrays (array1 and array2) of objects. The third argument, _.isEqual, is a custom comparator function that is used to compare the objects in the arrays. The function returns an array containing the objects that exist in only one of the arrays. In this case, the result is [{ x: 3, y: 3 }], which is the object that only exists in array2.
