Lodash _.xorWith() Method

The _.xorWith() method is similar to _.xor() method except that it accepts comparator which is invoked to compare elements of arrays. Order of result values which is determined by the order they occur in the arrays.

Syntax:

_.xorWith([arrays], [comparator])

Parameters: This method accepts two parameters as mentioned above and described below:

• [arrays]: This parameter holds the arrays to inspect.
• [comparator] (Function): This parameter holds the comparator invoked per element and is invoked with two arguments(arrVal, othVal).

Return Value: This method is used to returns the new array of filtered values.

Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library in the file.

javascript

// Requiring the lodash library
const _ = require("lodash");

// Original array

var objects = [{ 'x': 3, 'y': 4 }, { 'x': 4, 'y': 3 }];
var others = [{ 'x': 3, 'y': 3 }, { 'x': 3, 'y': 4 }];

// Use of _.xorWith()
// method

let gfg = _.xorWith(objects, others, _.isEqual);


// Printing the output
console.log(gfg);

Output:

[{ x: 4, y: 3 }, { x: 3, y: 3 }]

Example 2:

javascript

// Requiring the lodash library
const _ = require("lodash");

// Original array

var objects = ([ 23, 34, 98 ], [ 34, 23 ]);
var obj = ([ 4, 6 ], [4, 34, 6, 98 ]);

// Use of _.xorWith()
// method

let gfg = _.xorWith(objects, obj, _.isEqual);

// Printing the output
console.log(gfg);

Output:

[ 23, 4, 6, 98 ]

Example 3:

javascript

// Requiring the lodash library
const _ = require("lodash");

// Original array

var obj1 = ([ 'p', 'q', 'r' ], [ 'u', 's', 't', 'u' ]);

var obj2 = ([ 'p', 'q', 'u', 's' ], [ 't', 'r', 'u' ]);

// Use of _.xorWith() method

let gfg = _.xorWith(obj1, obj2, _.isEqual);

// Printing the output
console.log(gfg);

Output:

[ 's', 'r' ]

Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
