This article mainly introduces the relevant knowledge of "how to achieve the intersection of two arrays in JavaScript". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to achieve the intersection of two arrays in JavaScript" can help you solve the problem.

The intersection of two arrays I

Given two arrays nums1 and nums2, return their intersection. Each element in the output must be unique. We can ignore the order of the output results.

Example 1:

Input: nums1 = [1pm 2je 2je 1], nums2 = [2je 2]

Output: [2]

Example 2:

Input: nums1 = [4JEI 9JEI 5], nums2 = [9Jet 4JEI 8JE4]

Output: [9pd4]

Explanation: [4pd9] is also acceptable.

Note:

1 aMub) let res = [] let key1 = 0, key2 = 0, index = 0 while / keep pushing while (key1) without two pointers reaching the boundary.

Nums2 [key2]) key2++else {res [index++] = Nums1 [key1] key1++key2++}} return res}; that's all for "how JavaScript achieves the intersection of two arrays". Thank you for reading.
