JS palindrome number (Likou++)

Given an integer x, return true if x is a palindromic integer; otherwise, return false.

A palindrome number is an integer that reads the same in forward order (from left to right) and reverse order (from right to left).

For example, 121 is a palindrome, but 123 is not.
