LeetCode: Intersection of Two Arrays Solution

Approach

Convert 2 array to set and find intersection

Implementation

1var intersection = function (nums1, nums2) {
2  const [set1, set2] = [new Set(nums1), new Set(nums2)]
3  const res = []
4
5  for (const num of set1) {
6    if (set2.has(num)) {
7      res.push(num)
8    }
9  }
