  • Last Updated : 02 Sep, 2020

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:

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

_.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.
