Lodash _.xor() method returns an array of the symmetric difference of given arrays i.e. it will create an array that contains an element that doesn’t exist in any other array.

Syntax:

_.xor(arrays);

Parameters:

  • arrays: This parameter holds one or more arrays that need to be inspected.

Return Value:

It returns an array of symmetric differences of given arrays.

Example 1: In this example, we are printing the xor of two arrays having values as integers by the use of the _.xor() method.

javascript

const _ = require('lodash');
 
let x = [3, 10, 100];
let y = [100, 10, 2];
 
let symmetricDifference = _.xor(x, y);
console.log(symmetricDifference);

                    

Output:

[ 3, 2 ]

Example 2: In this example, we are printing the xor of three arrays having values as integers by the use of the _.xor() method.

javascript

const _ = require('lodash');
 
let x = [3, 10, 100]
let y = [100, 10, 2];
let z = [10, 500, 3];
 
let symmetricDifference = _.xor(x, y, z);
console.log(symmetricDifference);

                    

Output:

[ 2, 500 ]

Example 3: In this example, we are printing the xor of two arrays having values as strings by the use of the _.xor() method.

javascript

const _ = require('lodash');
 
let js = ['web', 'mobile-app'];
let python = ['machine-learning', 'web'];
let c = ['basic-programming', 'system-app'];
let java = ['mobile-app', 'web', 'basic-programming'];
 
let symmetricDifference = _.xor(js, python, c, java);
console.log(symmetricDifference);

                    

Output:

[ 'machine-learning', 'system-app' ]

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