9. Palindrome Number - JavaScript Solution - by Abu Saleh Faysal

Checking "Palindrome number" is a very widespread problem. Compared to the other languages, I found it easier to solve this problem with JavaScript.


Step 01: Convert x into string using toString().
Step 02: Split the string using split().
Step 03: Reverse the string using reverse().
Step 04: Join the string using join().
Step 05: Convert the string into number using Number().
Step 06: Check whether the number is equal to the parameter x or not.

 * @param {number} x
 * @return {boolean}
var isPalindrome = function (x) {
    return x === Number(x.toString().split("").reverse().join(""));
