How to use xor function In Lodash

Syntax:
_.xor([arrays])
Example: The below example uses the xor function to remove duplicate elements from an array using Lodash.
const _ = require('lodash');
let arr =
["apple", "mango", "apple",
"orange", "mango", "mango"];
let res = _.xor(arr, []);
console.log(res);
Output:
[ 'apple', 'mango', 'orange' ]
