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.
