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.

Solution:

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(""));
};
