This article mainly introduces the relevant knowledge of "how to use JS to judge whether integer x is a palindrome number". The editor shows you the operation process through an actual case. The method of operation is simple and fast, and it is practical. I hope this article "how to use JS to judge whether integer x is a palindrome number" can help you solve the problem.

Title

Give you an integer x, and return true if x is a palindrome integer; otherwise, return false.

The number of palindromes means that the positive order (from left to right) and the reverse order (from right to left) are the same integers. For example, 121 is a palindrome, but 123 is not.

Example 1:

Input: X = 121. output: true

Example 2:

Input: X =-121. output: false explanation: read from left to right, which is-121c. Read from right to left, 121 -. So it's not a palindrome.

Example 3:

Input: X = 10 output: false explanation: read from right to left, which is 01. So it's not a palindrome.

Example 4:

Input: X =-101. output: false
