//     349. Intersection of Two Arrays
//
//
// Given two arrays, write a function to compute their intersection.
//
//     Example 1:
//
// Input: nums1 = [1,2,2,1], nums2 = [2,2]
// Output: [2]
// Example 2:
//
// Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4]
// Output: [9,4]
// Note:
//
//     Each element in the result must be unique.
//     The result can be in any order.
let intersection = function(nums1, nums2) {
  let array = new Set(nums1.filter(val => nums2.includes(val)));

  return [...array];
};
