ES6 - Array intersection, Difference, symmetric => using Arrow Function

ES6 - Array intersection, Difference, symmetric =>
-----------------------------------------------------------------
There is a better way using ES6:
Intersection
============
 let intersection = arr1.filter(x => arr2.includes(x));
 For [1,2,3] [2,3] it will yield [2,3]. On the other hand, for [1,2,3] [2,3,5] will return the same thing.

Difference
==========
let difference = arr1.filter(x => !arr2.includes(x));
For [1,2,3] [2,3] it will yield [1]. On the other hand, for [1,2,3] [2,3,5] will return the same thing.

symmetric difference
====================
let difference = arr1.filter(x => !arr2.includes(x)).concat(arr2.filter(x => !arr1.includes(x)));
