Given an integer x, return true if x is a palindrome, and false otherwise.

EXPLANATION CODE:
1) This is a JavaScript function that checks if a given integer x is a palindrome or not. A palindrome is a word, number, or sequence of characters that reads the same backward as forward.

2) The first thing this function does is convert the integer to a string by using the toString() method, so we can manipulate it as a sequence of characters.

3) Then, the function uses the split("") method to convert the string into an array of characters. This array is then reversed using the reverse() method, and finally joined back together into a string using the join("") method.

4) The rigorous equality operator === is used to compare this new string to the original string. If they are identical, the function returns true, indicating that the original string was a palindrome. Otherwise, false is returned.
