0 0 1 minute read

The _.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: This function accepts one or more parameters as mentioned above and described below:

arrays: This parameter holds one or more arrays that need to inspect.

Return Value: It returns an array of symmetric difference of given arrays.

Example 1:

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

Here, const _ = require('lodash') is used to import the lodash library into the file.

Output:

[ 3, 2 ]

Example 2:

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:

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);
