Here, we are going to learn how to check whether a given number is palindrome or not in JavaScript.
Palindrome numbers are those numbers that are equal to their reverse value I.e., the numbers that remain the same when their digits are reversed. The Palindrome numbers are also known as numeral palindrome numbers). For example, 12321 is a Palindrome number, because when we reverse its digits...
