class Solution {
    /**
     * @param {number[]} nums1
     * @param {number[]} nums2
     * @return {number[]}
     */
    intersection(nums1, nums2) {
        const nums1Set = new Set(nums1);
        const nums2Set = new Set(nums2);
        const intersection = nums1Set.intersection(nums2Set);
        return intersection;
    }
}

Returns the error:

TypeError: arr1.slice is not a function

Using the other 2026 Set methods return similar errors. These are supported by Node 22. The JS item in the language dropdown states it's using Node 22.08.
